Chemical Structure

4-Fluoro-3-methoxy-5-methylbenzoic acid methyl ester CAS 950525-97-0 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Fluoro-3-methoxy-5-methylbenzoic acid methyl ester.

CATO supplies 4-Fluoro-3-methoxy-5-methylbenzoic acid methyl ester (CAS 950525-97-0), a certified reference material (molecular formula C10H11FO3, MW 198.19 g/mol) for analytical method development and quality control.

Structurally, 4-Fluoro-3-methoxy-5-methylbenzoic acid methyl ester (C10H11FO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 198.19 g/mol, it falls into the medium-molecular-weight range. 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), 4-Fluoro-3-methoxy-5-methylbenzoic acid methyl ester 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.
