Chemical Structure

2-Fluoro-3-methoxybenzoic acid CAS 137654-20-7 chemical structure

Description

The occurrence of 2-Fluoro-3-methoxybenzoic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-Fluoro-3-methoxybenzoic acid (CAS 137654-20-7), a certified reference material (molecular formula C8H7FO3, MW 170.14 g/mol) for analytical method development and quality control.

Structurally, 2-Fluoro-3-methoxybenzoic acid (C8H7FO3) 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 170.14 g/mol, it falls into the medium-molecular-weight range. 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), 2-Fluoro-3-methoxybenzoic acid 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.
