3-Methyl-1-butanol (Isoamyl Alcohol) 99% / 99.5% / ≥99.9% CAS No. 123-51-3 Industrial & Pharmaceutical Grade

This high-purity 3-Methyl-1-butanol, available in 99%, 99.5%, and ≥99.9% concentrations, is produced via advanced fractionation from fusel oil or through oxo synthesis technologies . It features excellent solvency power, moderate evaporation rate, and a characteristic pungent, winey, fruity odor . As a branched-chain primary alcohol, it is widely used as a solvent in organic synthesis, a key component in molecular biology for nucleic acid extraction, a flavoring agent in the food industry, and an intermediate in pharmaceutical manufacturing . Its high purity and consistent quality make it ideal for critical applications requiring precise solvent properties. Each batch is rigorously tested using GC analysis to ensure consistent quality meeting industrial, pharmaceutical, and molecular biology standards.
