di-tert-butyl dicarbonate

Di-tert-butyl dicarbonate (CAS 24424-99-5 ), commonly known as Boc₂O or BOC-anhydride, is a reagent used across pharmaceutical synthesis and biotechnology to introduce the tert-butoxycarbonyl protecting group onto amines. This function is central to controlled peptide assembly and API manufacturing, where selective protection of reactive sites determines synthetic yield and product purity in complex chemical processes. In pharmaceutical manufacturing, Boc₂O is used to protect amine groups during multi-step synthesis of active pharmaceutical ingredients, preventing unwanted side reactions at critical stages of development. Peptide synthesis relies heavily on Boc chemistry, particularly in solid-phase and solution-phase processes producing therapeutic peptides and amino acid derivatives for various medical applications. Biotechnology workflows use it to modify proteins, linkers, and bioconjugates where reversible amine protection is required. It also appears in agrochemical and specialty chemical synthesis for clean transformations. Di-tert-butyl dicarbonate is supplied as a liquid or low-melting solid, with liquid form being the standard commercial presentation for bulk handling and efficient industrial processing. It is available in reagent-grade and high-purity pharmaceutical-grade specifications suited to GMP manufacturing environments. Packaging ranges from laboratory quantities up to drum-scale supply for operations. Contact us for supply of di-tert-butyl dicarbonate Request Quote
