Methyl 3-Methoxybenzoate CAS 5368-81-0 chemical structure

Description

CATO manufactures Methyl 3-Methoxybenzoate 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.

Methyl 3-Methoxybenzoate (CAS 5368-81-0) is a high-purity analytical reference standard with the molecular formula C9H10O3 and a molecular weight of 166.17 g/mol.

Methyl 3-Methoxybenzoate (C9H10O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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.
