Sec-butyl alcohol, also recognized by its IUPAC name 2-butanol, is a secondary alcohol with the chemical formula C4H10O. It exists as a flammable, colorless liquid and is known for its moderate solubility in water and complete miscibility with many organic solvents. The compound is particularly interesting due to its chirality; it possesses a stereocenter, meaning it can exist as two enantiomers: (R)-(-)-butan-2-ol and (S)-(+)-butan-2-ol. The racemic mixture (a 1:1 combination of both enantiomers) is commonly encountered, but specific industrial and research applications often require a particular enantiomer, such as (2S)-butan-2-ol (CAS 4221-99-2).

The industrial production of sec-butanol often involves the hydration of butenes. While its main large-scale application is as a precursor for methyl ethyl ketone (MEK), a vital solvent, its use extends to other areas. Esters of sec-butanol, for instance, are utilized in the flavor and fragrance industry due to their pleasant aromas. Furthermore, in fine chemical synthesis, enantiomerically pure forms like (2S)-butan-2-ol are indispensable for creating complex chiral molecules used in pharmaceuticals, agrochemicals, and advanced materials. The ability to buy these specific chiral forms is critical for achieving stereospecific outcomes in synthesis.

For businesses looking to procure sec-butyl alcohol or its specific enantiomers, identifying a trustworthy manufacturer is crucial. Chemical suppliers in China are a significant source for these materials, offering competitive pricing and a wide range of product grades. When selecting a supplier, consider factors such as product purity, adherence to safety standards, and the availability of technical documentation like Certificates of Analysis. Obtaining a free sample can also be beneficial for evaluating product quality before placing a large order. Understanding the CAS numbers and exact specifications required for your intended application will facilitate a smoother purchasing process.
