Small Molecule Manufacturing
We help pharmaceutical innovators bring APIs and intermediates from development to commercial reality. With more than 50 years of GMP manufacturing experience and expertise in advanced chemistry, our small molecule specialists deliver scalable solutions spanning process development, HPAPI, continuous flow, and biocatalysis.

One Partner, Every Stage
From late-stage development to commercial manufacturing and final API micronization, we act as one integrated partner across the small molecule lifecycle. The majority of our activities support Phase III and commercial products, where reliability, compliance, and supply continuity are critical.
In parallel, we selectively engage in Phase I–II programs, where strategic route redesign and sustainability improvements unlock maximum value early on. Projects are seamlessly managed across batch and continuous flow, including process intensification where beneficial.
Beyond small molecules, we also integrate peptides and oligonucleotides within the same ecosystem, ensuring continuity, flexibility, and performance at every stage.
What Sets Our Small Molecule Services Apart

Deep Expertise in Challenging Chemistry
We combine deep expertise in hazardous chemistries — such as azide, nitration, and hydrogenation — with a highly solution-driven mindset. We proactively think alongside our customers, flexibly adapting to evolving needs to deliver safe, robust, and scalable processes up to OEB5.
Trusted & Reliable for Over 50 Years
With over 50 years of experience, we are a trusted partner for reliable API supply at the highest quality standards. Our strong regulatory track record is matched by open, transparent communication, building long-term trust through consistent performance and close customer collaboration.
Innovative Approaches to Manufacturing

API Development and Manufacturing Services
Customers come to us when the chemistry is complex, the commercial launch needs peace of mind, the process must improve, or sustainability targets seem out of reach. Combining advanced process development expertise with proven commercial manufacturing capabilities, we help pharmaceutical partners transform complex APIs and intermediates into robust, scalable, and more sustainable commercial products.
Development and Manufacturing Facilities
Three sites across Belgium and India provide specialized development and manufacturing capabilities for complex small molecule programs.

Balen, Belgium
Balen supports commercial GMP manufacturing of small molecule APIs and continuous flow chemistry technologies. Processes built for scale-up, sustainability, and long-term supply.

Wetteren, Belgium
Wetteren provides small molecule process development, GMP manufacturing capabilities, and continuous flow chemistry. Supporting complex chemistries and manufacturing requirements for scale-up and commercial production.

Visakhapatnam, India
Visakhapatnam provides commercial manufacturing of small molecule intermediates, supporting GMP production for global programs.

Our Approach to Continuous API Improvement
We support API programs across the full lifecycle — not simply by scaling processes, but by continuously unlocking new value as products evolve. Driven by an operational excellence mindset, our teams proactively improve yield, robustness, safety, sustainability, and cost competitiveness through structured continuous improvement programs.
We are particularly strong in transforming customer processes into fundamentally safer and more sustainable manufacturing routes, leveraging continuous flow, biocatalysis and atom-efficient chemistry, supported by dedicated process safety expertise and proprietary sustainability assessment tools.

Customer Stories
Real programs. Real outcomes. Anonymized to protect customer confidentiality — source-confirmed internal case data.
Top-10 Pharma: Faster Scale-Up, Better Process
A top-10 pharmaceutical company needed to rapidly scale an API program without compromising quality, safety, sustainability, or time-to-market. Rather than simply transferring the process, ABPS challenged the route itself — identifying opportunities to improve manufacturability, robustness, and environmental performance before scale-up.
Following a successful NPI introduction, our Operational Excellence mindset continued to unlock improvements in yield, process consistency and lifecycle economics. The outcome was not just a successful launch, but a more competitive, resilient and sustainable manufacturing process built for long-term commercial success.
Commercial Product: Cost Competitiveness Without Supply Risk
A commercial product facing increasing cost pressure required a more competitive manufacturing model without introducing supply-chain risk. Leveraging the ABPS Belgium–India network, we implemented for our customer an internal transfer to Vizag while retaining the same project management structure, process knowledge, and quality standards.
The result was a lower-cost supply model, uninterrupted product availability and continued regulatory confidence — delivering both improved economics and the peace of mind of this long-term partner.
Frequently Asked Questions
How do you manage technology transfer and project onboarding?
Every project starts with a structured kick-off that establishes clear objectives, responsibilities, and timelines. From there, dedicated project management, biweekly governance meetings, and agreed reporting keep all stakeholders aligned. Every campaign concludes with a joint performance review covering both technical outcomes and collaboration effectiveness. This operational excellence-driven approach ensures rapid knowledge transfer, transparent communication, and continuous improvement from onboarding through commercial supply.
Will I have clear points of contact throughout the project?
Yes. Every customer benefits from two dedicated contacts: a Key Account Manager for commercial matters and a Project Manager for technical and operational execution. In parallel, direct interactions between the customer and Aji Bio-Pharma subject matter experts are actively encouraged. This combination of clear accountability and open communication enables faster decisions, stronger alignment, and more effective problem-solving throughout the project lifecycle.
Are there limitations to the types of projects you can handle?
Very few. From hazardous reagents and highly potent compounds to quality-critical, safety-sensitive and environmentally demanding processes, we routinely support projects that push the boundaries of pharmaceutical manufacturing. By combining advanced containment, process safety expertise, continuous flow and biocatalysis, we can safely develop, scale and manufacture an exceptionally broad range of APIs and intermediates. The added advantage: customers often improve both manufacturing performance and sustainability metrics, supporting increasingly ambitious Scope 3 targets at the same time.
How do you ensure sufficient manufacturing capacity for my product?
Capacity planning starts with transparency. Through regular risk-adjusted forecasting and close customer collaboration, we translate anticipated demand into long-term capacity strategies across our manufacturing network. This enables proactive resource planning while maintaining flexibility for changing market conditions. The result is a shared multi-year supply vision that minimizes supply risk, supports on-time-in-full delivery, and gives customers the confidence to plan their business with certainty.
How do you approach analytical development and analytical support?
Analytical development is integrated from the earliest stages of every project. Depending on customer needs, we can transfer existing methods or develop and validate them internally using an extensive analytical toolbox and advanced PAT capabilities. Because analytical expectations continue to evolve throughout development and commercialization, we focus on early alignment and transparent communication, helping customers reduce risk, avoid delays, and maintain control over quality throughout the product lifecycle.
