  • Applications

    Sec-butylamine (CAS 13952-84-6) is a primary amine used as an organic synthesis intermediate across multiple industries. It is commonly employed as a building block for pharmaceutical and agrochemical intermediates, and serves as a starting material for the preparation of carbamates and ureas used in polymer and coating formulations. It may be used as a reactive amine component in epoxy resin systems, acting as a curing or crosslinking agent in coatings and adhesives. It also serves as a fragrance intermediate in perfumery and flavor chemistry, where amines are leveraged to access aroma compounds. In industrial manufacturing, sec-butylamine is regarded as a versatile building block with applications governed by local regulations and formulation limits.
