Our Approach

Proven API Process Development Strategy

We combine chemical expertise with systematic process engineering to deliver a synthetic route that meets your purity, yield, and timeline targets.

Route Scouting & Process Design

We evaluate multiple synthetic pathways, considering IP position, safety, atom efficiency, and cost of goods to select the most viable route for your target API.

  • Evaluation of literature and novel synthetic routes
  • Identification of critical process parameters (CPPs)
  • Solvent and reagent selection for impurity control

Process Optimization & Scale-Up

Through design of experiments (DoE) and risk assessment, we optimize reaction conditions, workup procedures, and purification to create a robust, scalable process.

  • DoE-based parameter screening and robustness studies
  • Process safety assessment and thermal hazard analysis
  • Scale-up from lab (grams) to pilot (kg) and commercial

Process Safety

We conduct systematic safety evaluations including reaction calorimetry and thermal stability testing to anticipate and mitigate hazards during scale-up.

Cost Optimization

By reducing step count, improving yields, and selecting cost-effective raw materials, we lower the cost of goods while maintaining quality.

Green Chemistry

We prioritize environmentally benign solvents, catalysis, and waste minimization strategies to meet sustainability goals without compromising performance.

Workflow

Engagement Journey

Our phased approach ensures clear milestones and continuous alignment with your program goals.

Kickoff & Route Scouting

We review your molecule's chemistry, regulatory environment, and prior art to propose viable synthetic routes and agree on selection criteria with your team.

Process Design & Optimization

Using DoE and risk-based experimentation, we optimize reaction conditions, workup, and isolation to maximize yield, purity, and reproducibility.

Scale-Up & Tech Transfer

We scale the optimized process in a pilot plant, confirm CPPs/CQAs, and prepare the technology transfer package for your manufacturing partner.

Process Validation Support

We assist in process validation protocol development, execute validation batches (as scoped), and compile the validation report for regulatory submission.

Ongoing Optimization & Lifecycle

After launch, we support continuous improvement, second-generation route development, and process robustness monitoring.

Applications

When to Engage API Process Development

Clinical Stage Optimization

Refine the process to meet specific requirements (as scoped), improve yield, and ensure reproducibility for Phase I and II clinical trial material.

  • Process optimization for increased yields and purity
  • Process validation readiness assessment
  • Technology transfer to clinical manufacturing site

Commercial Scale-Up

Finalize the commercial manufacturing process, conduct process validation, and prepare regulatory documentation for NDA/BLA submission.

  • Commercial route design and cost reduction
  • End-to-end process validation
  • Lifecycle management and continuous improvement
FAQ

Common Questions

Answers to frequent queries about our API process development and optimization services.

  • API process development is the systematic design and optimization of a synthetic route to manufacture an active pharmaceutical ingredient. It ensures that the process is efficient, reproducible, economical, safe, and environmentally friendly, while meeting regulatory standards. Proper development reduces scale-up risk and enables consistent production of high-quality drug substance.

  • We evaluate multiple pathways based on criteria including cost of goods, safety, atom efficiency, IP position, and scalability. Route scouting involves literature review, retrosynthetic analysis, and expert assessment to select the most promising route for further optimization. Selection is project-specific and reviewed with your team.

  • Yes, our service includes scale-up from laboratory to pilot scale and technology transfer to your manufacturing partner. We prepare batch records, train personnel, and support the first batches (if scoped). The level of support is defined during consultation to match your program's needs.

  • We conduct process safety assessments including reaction calorimetry, differential scanning calorimetry (DSC), and thermal stability studies. These evaluations identify thermal hazards and help define safe operating conditions, preventing incidents during scale-up. Safety data is documented in the process package.

  • Yes, we provide optimization services for existing processes to improve yield, reduce cost, or address quality issues. Our approach involves analyzing current CPPs, conducting targeted DoE studies, and recommending changes to enhance robustness and efficiency. The scope is tailored to your specific objectives.
