Methyl 2-chloro-5-hydroxy-4-methylbenzoate CAS 2007917-41-9

Description

The occurrence of Methyl 2-chloro-5-hydroxy-4-methylbenzoate 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.

Methyl 2-chloro-5-hydroxy-4-methylbenzoate (CAS 2007917-41-9) is a high-purity analytical reference standard with the molecular formula C9H9ClO3 and a molecular weight of 200.62 g/mol.

Methyl 2-chloro-5-hydroxy-4-methylbenzoate (C9H9ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 2-chloro-5-hydroxy-4-methylbenzoate 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.
