sec-Butanol (SBA)
CAS Number: 78-92-2
sec-Butanol (SBA, ≥99.0%) is a secondary alcohol that serves as the primary industrial precursor for methyl ethyl ketone (MEK) via catalytic dehydrogenation. It is also used as a solvent in lacquers, printing inks, and as a chemical intermediate in the production of sec-butyl acrylate and other esters.
