1,4-Butanediol is a clear, hygroscopic diol with a mild odor, widely used as a solvent, intermediate in polymer production (e.g., polyurethanes, polyesters), and in pharmaceuticals, cosmetics, and electronic chemicals. Its largest industrial outlet is as a feedstock for tetrahydrofuran (THF), and it is also a key monomer for poly(butylene terephthalate) plastics. It functions as a building block for spandex fibers, plasticizers, and solvent-based coatings. CAS 110-63-4, molecular formula HO(CH2)4OH, molecular weight 90.12 g/mol. Stored at ambient conditions, it carries a Warning signal word, as it is harmful if swallowed (H302) and may cause drowsiness or dizziness (H336). Molekula supplies 1,4-Butanediol from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
