Drug Substance (API) Synthesis - Quotient Sciences

Drug Substance Services from Quotient Sciences

Process Research and Development

Highly trained and experienced Quotient Sciences chemists support all aspects of drug substance development, selecting and developing optimum synthetic routes for drug substance manufacturing also known as API manufacturing (Active Pharmaceutical Ingredient).

We combine rapid route selection with the implementation of innovative technological solutions to produce the shortest, most efficient and most scalable pathway to a drug substance. Our focus is on process velocity and economy, product purity, process scalability, and safety. The drug substance can then be scaled to multi-kilogram quantities to support direct client supply, or as part of an integrated in-house drug substance/drug product package to support clinical trials or full-scale commercialization programs.

Quotient Sciences' philosophy targets optimal velocity for drug substance delivery, to ensure rapid drug substance supply for urgent clinical trial needs while enhancing process efficiency and robustness to lower costs and generate higher purity. Our work also involves defining the best route for product manufacturing scalability.

Drug Substance Stability Testing - Quotient Sciences
Stability Testing

Stability testing provides evidence of how time and changes in the environment affect the quality of a drug substance. We produce high-quality stability data through a combination of analytical, microbiological, and material science methodologies. Our service is supported by state-of-the-art facilities, including walk-in, ICH-compliant stability chambers and several smaller, reach-in units. ICH-compliant photo-stability testing equipment is also available to study the effects of light stress on materials and packaging.
