Regulatory Differences Between API and Intermediate Manufacturing: A Practical Guide
Regulatory differences between API and intermediate manufacturing under ICH Q7, FDA, EMA, and NMPA. GMP boundaries, DMF filing, starting material justification.
In today’s era, breakthroughs in pharmaceuticals often depend on mastering complex chemical synthesis. Tianming Pharmaceutical is proud to announce a milestone achievement: the successful commercialization of orforglipron intermediates.
After years of relentless research, strategic problem-solving, and cross-functional collaboration, our team overcame the technical and logistical obstacles that once hindered the global production of this critical compound.
Today, we share our journey and capabilities with the global scientific community and industry partners.
Orforglipron is a next-generation therapeutic drug gaining increasing attention in metabolic disorder research, whose synthesis relies on a complex network of intermediates.
These intermediates typically feature unstable molecular structures and stringent production conditions, posing long-standing challenges for manufacturers. A minor error in temperature control, catalyst selection, or purification protocols could render an entire batch of the process ineffective, making scalable production a long-sought-after goal for chemists worldwide.
At Tianming Pharmaceuticals, we recognized early on that mastering the intermediates for Gliclazide requires not only chemical expertise but also redefining the possibilities of API production.
Our R&D team first analyzed the molecular structure of Gliclazide, identifying three core intermediates as key pathways.
Catalyst Optimization: Traditional palladium catalysts were inefficient for synthesizing intermediates. After multiple iterations, our team pioneered a catalyst system that reduced reaction time by 60% while maintaining a 99% ee value (enantiomeric excess).
Stability Breakthrough: We designed a proprietary solvent system to inhibit hydrolysis, significantly reducing degradation rates during post-processing.
Process Enhancement: By integrating continuous flow chemistry technology, we increased yield from 68% (batch) to 89% at a 10x scale.
Every kilogram of orforglipron intermediates produced at our cGMP-certified facility undergoes the following processes:
Heavy metal screening via ICP-MS
Residual solvent testing in accordance with ICH Q3C guidelines
