Chemical Structure

Methyl 3,5-dichloro-4-hydroxybenzoate hydrate CAS 287399-19-3 chemical structure

Description

The occurrence of Methyl 3,5-dichloro-4-hydroxybenzoate hydrate is closely related to 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.

CATO supplies Methyl 3,5-dichloro-4-hydroxybenzoate hydrate (CAS 287399-19-3), a certified reference material (molecular formula C8H6Cl2O3H2O, MW 239.05 g/mol) for analytical method development and quality control.

The molecular framework of Methyl 3,5-dichloro-4-hydroxybenzoate hydrate (C8H6Cl2O3H2O) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Methyl 3,5-dichloro-4-hydroxybenzoate hydrate 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.
