1,4-Butanediol CAS:110-63-4

1,4-Butanediol (BDO), with the molecular formula C4H10O2, is a synthetic organic compound that belongs to the family of diols due to its two hydroxyl functional groups. Typically appearing as a clear, viscous liquid at room temperature, BDO is known for its hygroscopic nature, meaning it readily absorbs moisture from the environment. One of the most significant applications of 1,4-butanediol is in the production of polymers. It serves as a key monomer in the synthesis of polybutylene terephthalate (PBT), a thermoplastic polymer renowned for its durability, chemical resistance, and excellent thermal stability. PBT is widely utilized in automotive components, electrical appliances, and consumer goods. BDO is also integral in the manufacture of polyurethane, a versatile class of polymers used in foams, coatings, adhesives, and elastomers. By participating in the formation of polyurethane prepolymers, BDO enhances mechanical properties, flexibility, and resistance to degradation, making it an essential ingredient in high-performance materials. In addition to its role in polymer production, 1,4-butanediol is employed as a solvent in various industrial applications. Its ability to dissolve a wide range of substances makes it valuable in the formulation of paints, coatings, and inks. Furthermore, BDO is utilized in the pharmaceutical and cosmetic industries, where it acts as an excipient or carrier, enhancing the solubility and bioavailability of active ingredients. Safety considerations are crucial when handling 1,4-butanediol, as exposure can cause irritation to the skin, eyes, and respiratory system. Therefore, proper safety precautions, including the use of personal protective equipment and adequate ventilation, should be observed. In summary, 1,4-butanediol is a highly versatile compound with essential applications in polymer production, solvent formulations, and the pharmaceutical industry, contributing to the development of a wide range of high-performance materials while necessitating careful handling protocols.
