2-amino-6-chloro-3-hydroxybenzoic acid CAS 629652-73-9

Description

The occurrence of 2-amino-6-chloro-3-hydroxybenzoic acid is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-amino-6-chloro-3-hydroxybenzoic acid (CAS 629652-73-9), molecular formula C7H6ClNO3 and molecular weight 187.58 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-amino-6-chloro-3-hydroxybenzoic acid (C7H6ClNO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 187.58 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.

As a certified reference material (CRM), 2-amino-6-chloro-3-hydroxybenzoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
