Chemical Structure

4-Methylthiophen-3-amine oxalate CAS 500100-74-3 chemical structure

Description

The occurrence of 4-Methylthiophen-3-amine oxalate is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 4-Methylthiophen-3-amine oxalate (CAS 500100-74-3), a certified reference material (molecular formula C5H7NSC2H2O4, MW 203.21 g/mol) for analytical method development and quality control.

The molecular framework of 4-Methylthiophen-3-amine oxalate (C5H7NSC2H2O4) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
