Sec-butanol, also known as 2-butanol (CAS 78-92-2 for the racemate, with specific enantiomers like (2S)-butan-2-ol, CAS 4221-99-2), is a versatile secondary alcohol with a broad spectrum of industrial and chemical applications. While its primary role in large-scale production is as a precursor to methyl ethyl ketone (MEK), a widely used industrial solvent, the utility of sec-butanol extends far beyond this singular function. Its unique chemical properties, including its moderate polarity, solubility characteristics, and chiral nature when in enantiomerically pure form, make it a valuable compound in various sectors.

As a solvent, sec-butanol is utilized in the production of lacquers, varnishes, and as a component in paint removers, although its use in consumer products has seen some decline due to regulatory considerations. In the realm of fine chemicals and organic synthesis, sec-butanol and its chiral variants, such as (2S)-butan-2-ol, serve as critical intermediates and building blocks. These chiral forms are especially important in the pharmaceutical and agrochemical industries for the synthesis of stereospecific molecules, where precise molecular configuration is key to efficacy and safety. Identifying a reputable supplier for these specialty grades is vital for consistent research and development outcomes.

Furthermore, esters derived from sec-butanol possess pleasant aromas and are employed in small quantities as flavorings and fragrances. The ability to purchase sec-butanol and its derivatives from reliable manufacturers, especially those based in China, offers a cost-effective solution for businesses requiring these materials in bulk. Understanding the specific CAS number and purity requirements is essential when sourcing sec-butanol for specialized applications. Whether for large-scale industrial processes or niche research projects, the adaptability of sec-butanol underscores its significance in the chemical industry. Businesses looking to buy this compound can benefit from the competitive market and advanced production capabilities available from leading chemical suppliers.
