In the complex landscape of pharmaceutical development, specific chemical compounds often play a disproportionately significant role. One such compound is identified by its CAS number: 431579-34-9, chemically known as (17a,20E)-17,20-[(1-Methoxyethylidene)bis(oxy)]-3-oxo-19-norpregna-4,20-diene-21-carboxylic Acid Methyl Ester. Understanding the properties and sourcing channels for this molecule is crucial for researchers, formulators, and procurement specialists in the pharmaceutical and fine chemical industries.
This specific chemical entity is characterized by its distinct molecular structure, which lends itself to being a valuable intermediate in various organic synthesis pathways, particularly within the pharmaceutical domain. Its common synonyms include variations of its chemical name and potentially research codes, such as YK11, though it's essential to verify specific context as YK11 might also refer to related research chemicals. For the purpose of pharmaceutical applications, the precise chemical nomenclature and CAS number are the definitive identifiers.
Key properties that make CAS 431579-34-9 valuable include its specified purity, often required to be ≥98.0% when used in pharmaceutical synthesis. It typically appears as a white powder, which is a common and convenient form for laboratory handling and industrial application. The physical form and purity are critical indicators for its suitability in demanding pharmaceutical manufacturing processes, where consistency is key to reproducibility and regulatory compliance.
When seeking to buy CAS 431579-34-9, it is paramount to engage with reputable manufacturers and suppliers. Companies specializing in pharmaceutical intermediates, particularly those with a strong presence in chemical manufacturing hubs like China, often offer this compound. It is advisable to look for suppliers who provide comprehensive product specifications, Certificates of Analysis (COAs), and robust quality control systems. Understanding the supplier's production capabilities and their commitment to quality assurance will ensure a stable and reliable source for your needs, whether for pilot studies or full-scale production. For procurement managers and research scientists, identifying these trusted partners is the first step towards successful project outcomes.
