Chemical Structure

Methyl 2,5-Dihydroxybenzoate CAS 2150-46-1 chemical structure

Description

CATO supplies Methyl 2,5-Dihydroxybenzoate (CAS 2150-46-1), a certified reference material (molecular formula C8H8O4, MW 168.15 g/mol) for analytical method development and quality control.

Based on its molecular formula C8H8O4, Methyl 2,5-Dihydroxybenzoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 168.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Methyl 2,5-Dihydroxybenzoate 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.
