Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 207.01 g/mol gives 2,3-Dichloro-6-hydroxybenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2,3-Dichloro-6-hydroxybenzoic acid (CAS 1806282-06-3), a certified reference material (molecular formula C7H4Cl2O3, MW 207.01 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2,3-Dichloro-6-hydroxybenzoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 207.01 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 2,3-Dichloro-6-hydroxybenzoic 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.
