Custom Development

Our process development chemists provide route scouting, process development, and process optimization services based on Design of Experiments (DoE) and Quality by Design (QbD) principles. We deliver APIs, key intermediates, and regulatory starting materials from gram to kilogram scale, supporting development milestones from early clinical stages through commercial manufacturing.

Route Scouting & Process Redesign

Explore new synthetic routes or redesign and optimize existing routes to reduce cost, improve quality, enhance process safety, and enable robust scalability.

Process Development & Optimization

Rapidly develop and optimize critical reaction steps using DoE and QbD principles, where appropriate.

Advanced Chemistry Technologies

Address challenging chemical transformations using technologies such as flow chemistry, photochemistry, enzymatic chemistry, and other advanced process technologies.

CQAs & CPPs

Through systematic experimentation and process understanding, our scientists identify the Critical Quality Attributes (CQAs) of an API and the Critical Process Parameters (CPPs) that influence them. This enables us to establish a robust design space with built-in flexibility, supporting consistent quality, accuracy, and reproducibility during scale-up and technology transfer to manufacturing.

Impurity Identification & Control

Synthesize, isolate, and characterize impurities; investigate their potential mechanisms of formation; and develop effective impurity purging and control strategies.

PAR & NOR Studies

Conduct Proven Acceptable Range (PAR) and Normal Operating Range (NOR) studies to establish robust operating conditions and support regulatory filings.

Process Safety Studies

Generate stability data, perform stress testing, and evaluate process safety using RC1mx, DSC, and TSU studies for both powder and liquid systems.

Technology Transfer

Seamlessly transfer optimized processes and associated knowledge to internal manufacturing plants for scale-up and commercial production.

Analytical Development

With expertise in analytical method development and advanced analytical instrumentation, we provide comprehensive analytical solutions to support NCE and API development across the product lifecycle.

  • Stability Studies
    Comprehensive stability studies conducted in accordance with ICH guidelines, including Zone IV conditions, to support shelf-life assessment, storage conditions, and regulatory requirements.

Process Safety Studies

Safety is embedded throughout our process development lifecycle. Our dedicated Process Safety team evaluates chemical and thermal hazards to identify risks early, optimize process conditions, and enable safe scale-up from laboratory to commercial manufacturing.

Systematic HAZOP studies and risk assessments to identify process hazards, evaluate risks, and establish effective control measures.

Comprehensive evaluation of reaction and thermal hazards using advanced calorimetric techniques to understand heat generation, accumulation, and decomposition risks.

Advanced studies for both liquid and powder systems to assess reaction behavior, thermal stability, dust explosion risks, and safe operating conditions.

Our Process and Powder Safety laboratory is equipped with RC1mx, TSU, DSC, Minimum Ignition Energy Test (MIE), Minimum Ignition Temp. Test (MIT), Layer Ignition Temp. Test (LIT), Ball Fall Hammer, capabilities for in-depth process safety evaluation.

Generating critical safety data to define safe operating parameters, support process optimization, and enable reliable scale-up to commercial manufacturing.
