For professionals in the pharmaceutical and fine chemical industries, identifying and sourcing critical intermediates like CAS 137688-21-2, also known as (S)-2-(But-3-en-1-yl)oxirane, is a daily challenge. This chiral epoxide is a valuable building block for organic synthesis, particularly in the development of pharmaceuticals and other complex organic molecules. As a buyer, your primary concerns will revolve around product purity, consistent supply, technical specifications, and competitive pricing. Understanding these factors is key to making informed purchasing decisions and securing a reliable supply chain for your projects.

The molecule's structure, C6H10O with a molecular weight of 98.14, features an oxirane ring and an alkene group, making it highly reactive and adaptable for various chemical transformations. When you buy CAS 137688-21-2, you are investing in a compound that can unlock intricate synthetic pathways. However, not all suppliers are created equal. The specification of '99% min' purity is a critical benchmark. Impurities can compromise downstream reactions, leading to lower yields and the need for costly purification steps. Therefore, it is essential to partner with a manufacturer that has robust quality control systems in place.

China has emerged as a significant global hub for chemical manufacturing, offering a vast array of intermediates at competitive prices. When seeking a supplier for (S)-2-(But-3-en-1-yl)oxirane, it is advantageous to consider established Chinese companies that specialize in pharmaceutical intermediates. These manufacturers often have the capacity and expertise to produce high-purity chemicals consistently. Buyers should look for suppliers who can provide detailed Certificates of Analysis (CoA) and are transparent about their manufacturing processes. Furthermore, the availability of a free sample allows for in-house verification of quality before a larger investment is made, a common practice for critical raw materials.

Procurement managers should also consider the logistical aspects. A reliable supplier will offer efficient worldwide delivery and responsive customer service. Understanding the storage conditions – typically an inert atmosphere at 2-8°C for this particular oxirane derivative – is also important to maintain its integrity from the point of manufacture to its use in your facility. By focusing on these key elements – purity, manufacturer reputation, price, and service – buyers can confidently source CAS 137688-21-2 and ensure the success of their research and manufacturing endeavors. Engaging with leading chemical suppliers can streamline the procurement process and foster long-term collaborative relationships.
