5-Methylthiophene-2,3-dicarboxylic Acid CAS 46029-22-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Methylthiophene-2,3-dicarboxylic Acid.

CATO supplies 5-Methylthiophene-2,3-dicarboxylic Acid (CAS 46029-22-5), a certified reference material (molecular formula C7H6O4S, MW 186.19 g/mol) for analytical method development and quality control.

Based on its molecular formula C7H6O4S, 5-Methylthiophene-2,3-dicarboxylic Acid 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 186.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
