Catecholborane

Catecholborane (CAS 274-07-7 ) is a cyclic organoboron reagent used as a selective hydroboration agent in synthetic chemistry. It delivers controlled boron addition to unsaturated substrates, enabling the preparation of boronate esters. These boronate esters are essential chiral intermediates that downstream processes require for complex molecular construction. In pharmaceutical synthesis, it is used to produce enantiomerically enriched boronic acid derivatives. These derivatives serve as building blocks for active pharmaceutical ingredients, including protease inhibitors and antifungal compounds. Asymmetric hydroboration with chiral rhodium or iridium catalysts relies on this boron source. This process allows for the generation of stereocenters with high selectivity during drug development. In agrochemical development, it supports the synthesis of boron-containing crop protection compounds at the research stage. It also functions as a catalyst precursor and initiator in certain boron-mediated polymerization processes within specialty materials research. The reagent is supplied as a liquid, typically handled under an inert atmosphere. Due to its moisture sensitivity, it is available in research quantities and in larger volumes for process chemistry and scale-up applications. Standard offerings include technical and high-purity grades for various uses. Purity specifications are commonly confirmed by NMR or GC analysis to meet pharmaceutical intermediate requirements. This ensures the material meets the rigorous standards necessary for sensitive chemical transformations and manufacturing. Contact us for supply of Catecholborane Request Quote
