Overview

1-butoxypropan-2-ol (CAS 5131-66-8) is an ether alcohol compound with excellent solvent properties and moderate volatility characteristics. This glycol ether derivative represents an important member of the propylene glycol monoalkyl ether family, offering valuable performance characteristics for industrial applications. With its molecular formula C7H16O2 and molecular weight of 132.2 g/mol, 1-butoxypropan-2-ol combines the polar hydroxyl group functionality with the hydrophobic butoxy chain, resulting in unique amphiphilic properties that make it particularly effective as a coupling solvent and surface-active agent. The compound exhibits moderate hazard classification under GHS regulations, presenting skin and eye irritation potential (Skin Irrit. 2; Eye Irrit. 2) with Warning signal word and GHS07 pictogram. Its ADR Class 3 classification indicates flammable liquid properties, requiring appropriate handling and storage precautions in industrial environments. These safety characteristics are typical for glycol ether compounds and necessitate proper personal protective equipment and ventilation systems during use. In industrial applications, 1-butoxypropan-2-ol serves primarily as a high-performance solvent in coating formulations, where its slow evaporation rate and excellent film-forming properties enhance surface quality. The compound also functions effectively in cleaning formulations and as a coupling agent in various chemical processes. Its solvent characteristics can be compared to other glycol ethers, though it offers distinct advantages over compounds like 2-methylpentane-2,4-diol in specific formulation requirements. OYSI provides reliable access to 1-butoxypropan-2-ol for European industrial customers, ensuring consistent quality and regulatory compliance for demanding technical applications.
