For researchers and production managers in the pharmaceutical sector, the reliable sourcing of specialized chemical intermediates is paramount. Among these, (3R,4S)-3-(2-Bromoacetyl)-4-ethyl-1-pyrrolidinecarboxylic acid phenylmethyl ester (CAS 1428243-26-8) stands out due to its critical role in the synthesis of Upatinib, a significant therapeutic agent. This article aims to guide buyers on essential considerations when looking to procure this vital compound, stressing the importance of purity and supplier integrity, particularly when sourcing from China.

When you need to buy (3R,4S)-3-(2-Bromoacetyl)-4-ethyl-1-pyrrolidinecarboxylic acid phenylmethyl ester, the primary concern must be product quality. The compound's CAS number, 1428243-26-8, identifies it specifically, but its purity and consistency are what truly matter for successful chemical synthesis. A minimum assay of 99% is often required for pharmaceutical intermediates to ensure that impurities do not interfere with downstream reactions or compromise the final product. This is especially true when preparing Upatinib intermediate, where even minor contaminants can lead to costly setbacks.

Understanding the chemical properties associated with this intermediate is also crucial for effective procurement and utilization. Its white powder appearance, specific molecular weight (354.24 g/mol), and characteristic functional groups, including the bromoacetyl moiety, dictate its handling and reactivity. Manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. provide detailed specifications, enabling informed purchasing decisions. These details are vital for anyone optimizing synthesis routes or conducting detailed chemical analysis.

Choosing the right chemical supplier is as important as selecting the right intermediate. When sourcing from China, reputable manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. offer significant advantages, including competitive pricing and robust manufacturing capabilities. They often possess extensive experience in producing complex organic compounds and understand the stringent quality control measures required for pharmaceutical intermediates. Looking for suppliers with a proven track record in export and adherence to international standards is a wise strategy.

The role of this intermediate extends beyond Upatinib. It's a valuable component in the broader field of API intermediate production and organic chemistry research. Its utility in creating imidazopyrrolopyrazine derivatives highlights its versatility. Therefore, establishing a strong relationship with a reliable manufacturer who can consistently supply this and other related chemicals is beneficial for long-term pharmaceutical R&D projects. By prioritizing quality and supplier reliability, buyers can ensure the smooth progress of their research and manufacturing efforts.
