5-Chloro-2-hydroxy-3-methoxybenzoic acid CAS 87964-77-0

Description

The occurrence of 5-Chloro-2-hydroxy-3-methoxybenzoic 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 5-Chloro-2-hydroxy-3-methoxybenzoic acid (CAS 87964-77-0), a certified reference material (molecular formula C8H7ClO4, MW 202.59 g/mol) for analytical method development and quality control.

Based on its molecular formula C8H7ClO4, 5-Chloro-2-hydroxy-3-methoxybenzoic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 202.59 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
