Process Optimization

Process optimization lays the foundation for scale-up and plays an important role in complying with current cGMP. Process optimization determines what is needed to scale up. The ultimate goal is to obtain better yields of chemicals and eliminate problems that may affect successful commercialization. Successful optimization of process can help customers get the right results the first time, which can save money and help you get to kilo labs faster with the right process. At BOC Sciences, our process department has employed QbD principles in API process development, striving to select the best route that is optimal for our customers. By optimize the API production process, we can reduce manufacturing risk and improve product quality and production efficiency. BOC Sciences is able to optimize and determine important process parameters, post-treatment methods, purification methods, impurity profile studies, process risk assessment and control, and process safety evaluation.

Benefits of process optimization

  • Eliminate process steps
  • Increase yields
  • Reduce cycle time
  • Produce higher quality products
  • Reduce costs

Our Services

To make it easier and better for researchers, BOC Sciences provides process optimization service in a competitive fashion. We have provided a more efficient way to increase the number of new drugs, greatly shorten the R&D cycle, and reduce the development costs. BOC Sciences has established a professional process safety team dedicated to process safety assessment in the chemical and pharmaceutical industry

  • Thoroughly study critical process parameters (CPPs) including temperature, concentration, time of reaction, crystallization, stirring rate, etc
  • Evaluate the thermal stability of samples by measuring the sample onset decomposition temperature, heat of fraction, and temperature and pressure changes during sample decomposition
  • Measure the reaction heat, exothermic rate, heat accumulation, reaction outgassing rate, etc
  • Perform safety analysis of the process
  • Determine the direction of process optimization and adjustment
  • Professional reaction heat risk assessment report

Key Equipment

Our team is skilled in operating multiple tools to develop robust, safe manufacturing processes and ensure safe manufacturing of APIs:


We apply it in the reaction characterization to help determine key process parameters including reaction enthalpy, thermal conversion rates, maximum temperature of the synthesis reaction (MTSR), ΔTad (adiabatic temperature rise), gas evolution and others

Differential scanning calorimetry (DSC)

DSC is used to measure the enthalpies associated with transitions and chemical reactions and determines the temperature at which these processes occur

Accelerated rate calorimetry (ARC)

ARC is applied to evaluate reaction calorimetry, secondary reactions of raw materials, intermediates and products (thermal stability assessment)
