For professionals in the pharmaceutical and chemical industries, securing reliable sources for critical intermediates like 6-Methyleneandrost-4-ene-3,17-dione (CAS 19457-55-7) is paramount. This compound, with its molecular formula C20H26O2 and a molecular weight of 298.42, plays a vital role in various synthesis pathways, particularly in steroid chemistry and as a pharmaceutical impurity standard.
When you are looking to buy 6-Methyleneandrost-4-ene-3,17-dione, several factors come into play. The purity of the chemical is non-negotiable. For pharmaceutical applications, especially when it serves as an intermediate or a reference standard for impurities like Exemestane Impurity E, high purity levels (often above 98% or 99%) are essential to ensure the integrity of downstream processes and final product quality. Manufacturers typically provide specifications detailing purity, appearance (often a pale yellow solid), melting point, and other physical properties such as density and boiling point.
The choice of supplier is equally critical. As a buyer, you need a manufacturer that can guarantee consistent quality, a stable supply chain, and transparent documentation. Working with a reputable manufacturer and supplier in China offers distinct advantages, including access to large-scale production capabilities and potentially more competitive pricing. For instance, understanding the typical price range for 6-Methyleneandrost-4-ene-3,17-dione in China can help in budget planning and negotiation.
Beyond just price, consider the supplier's experience and their ability to provide comprehensive support, including Certificates of Analysis (CoA), Material Safety Data Sheets (MSDS), and assistance with regulatory compliance. When you make a purchase inquiry for CAS 19457-55-7, be prepared to discuss your specific needs regarding quantity, packaging, and delivery timelines. Many suppliers offer bulk quote options, catering to both research and industrial-scale demands.
Ultimately, a successful procurement of 6-Methyleneandrost-4-ene-3,17-dione hinges on a thorough evaluation of potential manufacturers and suppliers. By focusing on purity, reliability, and clear communication, you can ensure that you acquire this important chemical intermediate efficiently and effectively.
