2-(3-Chloro-2-methylphenyl)acetic acid CAS 35703-39-0

Description

The occurrence of 2-(3-Chloro-2-methylphenyl)acetic acid 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.

CATO supplies 2-(3-Chloro-2-methylphenyl)acetic acid (CAS 35703-39-0), a certified reference material (molecular formula C9H9ClO2, MW 184.62 g/mol) for analytical method development and quality control.

Structurally, 2-(3-Chloro-2-methylphenyl)acetic acid (C9H9ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine 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 184.62 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
