3-(5-((M-tolyloxy)methyl)-1,3,4-thiadiazole-2-carboxamido)benzoic acid CAS 1142202-75-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(5-((M-tolyloxy)methyl)-1,3,4-thiadiazole-2-carboxamido)benzoic acid.

3-(5-((M-tolyloxy)methyl)-1,3,4-thiadiazole-2-carboxamido)benzoic acid (CAS 1142202-75-2) is a high-purity analytical reference standard with the molecular formula C18H15N3O4S and a molecular weight of 369.39 g/mol.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 3-(5-((M-tolyloxy)methyl)-1,3,4-thiadiazole-2-carboxamido)benzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 369.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
