Chemical Structure
Description
(5-Amino-2,4-dichlorophenyl)boronic acid (CAS 948592-69-6), molecular formula C6H6BCl2NO2 and molecular weight 205.83 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (5-Amino-2,4-dichlorophenyl)boronic acid (C6H6BCl2NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 205.83 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (5-Amino-2,4-dichlorophenyl)boronic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
