For procurement managers and R&D scientists in the chemical and pharmaceutical industries, securing a consistent supply of high-quality raw materials is paramount. (2S)-butan-2-ol (CAS 4221-99-2), a vital chiral alcohol, is one such compound. Its specific stereochemistry makes it indispensable for asymmetric synthesis, pharmaceutical development, and the creation of advanced materials. When it comes to purchasing this chemical, understanding what to look for in a supplier and product is key to ensuring project success.

The first crucial factor when you intend to buy (2S)-butan-2-ol is purity. Most applications, especially in pharmaceuticals, demand high enantiomeric excess (ee) and overall chemical purity, often exceeding 95%. Reputable manufacturers will readily provide Certificates of Analysis (CoA) detailing these specifications. The CAS number, 4221-99-2, serves as a universal identifier, ensuring you are procuring the correct stereoisomer.

Another critical aspect is the reliability of the supplier. Look for manufacturers with a proven track record in producing and supplying specialty organic chemicals. Companies that offer robust quality control, efficient logistics, and responsive customer service are ideal partners. Sourcing from China has become increasingly common due to competitive pricing and manufacturing scale. However, due diligence is essential to select a manufacturer that adheres to international quality standards and offers transparent communication. Obtaining a free sample before committing to larger quantities is a prudent step.

Understanding the various applications of (2S)-butan-2-ol, from its role as a chiral building block to its use as a specialized solvent or intermediate, will help procurement teams assess their needs accurately. By prioritizing suppliers who can provide detailed product information, consistent quality, and competitive pricing for this essential chiral alcohol, businesses can effectively manage their supply chain and accelerate their research and production efforts.
