2-Methoxy-5-methylthiobenzoicacid CAS 61694-97-1 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 2-Methoxy-5-methylthiobenzoicacid.

CATO supplies 2-Methoxy-5-methylthiobenzoicacid (CAS 61694-97-1), a certified reference material (molecular formula C9H10O3S, MW 198.24 g/mol) for analytical method development and quality control.

Based on its molecular formula C9H10O3S, 2-Methoxy-5-methylthiobenzoicacid contains a sulfone group, 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 198.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
