Product Core Data

Copper(I) bromide (CuBr), CAS 7787-70-4, Mw 143.45, appears as a white to off-white crystalline powder that slowly turns green on exposure to air. Its high surface area and variable oxidation state deliver excellent catalytic activity and ligand-free selectivity, making CuBr a widely used copper(I) salt in organic synthesis and materials science.

Catalysis:  Ullmann C–N/C–O/C–S couplings, Sandmeyer transformations, click chemistry

Pharmaceutical intermediates:  synthesis of antibiotics, antitumour agents, heterocyclic APIs

Agrochemicals:  catalyst for manufacture of brominated insecticides and fungicides

Organic synthesis:  atom-transfer radical addition (ATRA) and ATRP initiator systems

Electronic materials:  precursor for conductive CuBr thin films and quantum-dot surfaces

R&D:  routine catalyst in academic and industrial laboratories
