Benzopinacol (BPN/LT) is a high-purity organic compound used as a thermal radical initiator: on heating, its central C–C bond breaks to give diphenylhydroxymethyl radicals, which initiate the curing of unsaturated polyester and vinyl resins. It is also employed in photoresists and as a precursor for photochemical reactions. Chemists also use it as an intermediate in organic synthesis. CAS 464-72-2, molecular formula C26H22O2, molecular weight 366.45 g/mol. Stored at ambient conditions. Signal word: Warning. Molekula supplies Benzopinacol-BPN/LT from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
