Description

2-Amino-5-bromopyridine (CAS No. 1072-97-5) is a high-purity organic compound with the molecular formula C₅H₅BrN₂, widely used as a versatile intermediate in pharmaceutical synthesis, agrochemical development, and advanced material research. This fine chemical features a pyridine core substituted with an amino group at the 2-position and a bromine atom at the 5-position, enabling diverse functionalization via cross-coupling reactions (e.g., Suzuki, Buchwald-Hartwig). Supplied as a crystalline solid with ≥97% purity (HPLC), it is packaged under inert conditions to ensure stability. Ideal for medicinal chemistry applications, its bromo-aminopyridine scaffold serves as a key building block for kinase inhibitors, heterocyclic APIs, and ligand design. Technical specifications include: molecular weight 173.01 g/mol, melting point 94-98°C, and storage recommendations of 2-8°C in a dry environment. Available in research (100mg-1g), development (5g-25g), and bulk (100g+) quantities with optional custom purity (99%+).
