In the intricate world of pharmaceutical development, chemical compounds are identified and categorized by unique identifiers, the most prominent being the CAS (Chemical Abstracts Service) number. CAS 204254-96-6 refers to Ethyl (3R,4S,5S)-4,5-Epoxy-3-(1-ethylpropoxy)Cyclohex-1-Ene-1-Carboxylate, a compound that plays a significant role as an intermediate in the synthesis of important pharmaceutical agents, most notably Oseltamivir. Understanding the properties and applications associated with this CAS number is crucial for anyone involved in pharmaceutical R&D or manufacturing.

Ethyl (3R,4S,5S)-4,5-Epoxy-3-(1-ethylpropoxy)Cyclohex-1-Ene-1-Carboxylate is a complex organic molecule, characterized by its specific stereochemistry and functional groups. Its primary utility lies in its role as a precursor in the multi-step synthesis of Oseltamivir, an essential antiviral drug used to treat and prevent influenza. The demand for this Oseltamivir intermediate is directly linked to the global need for effective influenza treatments. Pharmaceutical companies and contract manufacturing organizations (CMOs) rely on a consistent supply of high-quality intermediates like this to maintain their production pipelines.

The quality of an intermediate is directly proportional to the quality of the final API. Therefore, sourcing CAS 204254-96-6 from a trusted Oseltamivir intermediate supplier is critical. Such suppliers, like NINGBO INNO PHARMCHEM CO.,LTD., must ensure high purity (typically above 95%) and rigorous quality control measures. This involves not only the chemical composition but also the physical form (often a white powder) and stability of the compound. The precision in chemical synthesis for Oseltamivir intermediate is a key differentiator for suppliers.

The availability of this chemical intermediate also fuels scientific research. Laboratories and R&D departments utilize CAS 204254-96-6 to explore novel synthetic methodologies, optimize existing processes, and develop new drug candidates. Its specific molecular structure makes it a valuable tool for organic chemists aiming to achieve complex molecular architectures. The ability to procure such high purity chemical intermediate for research purposes allows for greater innovation and efficiency in the early stages of drug discovery.

In conclusion, the CAS number 204254-96-6 represents more than just a designation; it signifies a critical component in the pharmaceutical supply chain. Ethyl (3R,4S,5S)-4,5-Epoxy-3-(1-ethylpropoxy)Cyclohex-1-Ene-1-Carboxylate, as an essential Oseltamivir intermediate, underscores the importance of quality and reliability in chemical manufacturing. For companies seeking to purchase or produce Oseltamivir, identifying and partnering with reputable Oseltamivir intermediate producers is a fundamental step towards ensuring product integrity and market success.
