Description
What is 1,4-Butanediol (BDO)?
1,4-Butanediol (BDO) is a versatile organic chemical compound with the molecular formula C₄H₁₀O₂. It is a clear, colorless, high-boiling and slightly viscous liquid with a mild odor, classified as a diol because it contains two terminal hydroxyl (-OH) functional groups. These hydroxyl groups provide excellent chemical reactivity, making BDO an important intermediate in numerous industrial manufacturing processes.
Due to its chemical structure and reactivity, 1,4-Butanediol is widely used as an important industrial intermediate in the production of high-performance polymers, solvents, elastic materials, and specialty chemicals.
One of the major applications of BDO is in the production of polybutylene terephthalate (PBT), an engineering thermoplastic known for its use in automotive components, electrical parts, and industrial applications. BDO is also used as a raw material for manufacturing derivatives such as tetrahydrofuran (THF), gamma-butyrolactone (GBL), and polyurethane-related materials.
Chemex Chemicals supplies 1,4-Butanediol (BDO) for industrial applications, supporting manufacturers and formulators requiring reliable chemical raw material sourcing.
