4-((5-Methyl-1,3,4-thiadiazol-2-yl)amino)-4-oxobut-2-enoic acid CAS 92340-62-0

Description

4-((5-Methyl-1,3,4-thiadiazol-2-yl)amino)-4-oxobut-2-enoic acid (C7H7N3O3S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

4-((5-Methyl-1,3,4-thiadiazol-2-yl)amino)-4-oxobut-2-enoic acid (CAS 92340-62-0), molecular formula C7H7N3O3S and molecular weight 213.21 g/mol, is a CATO reference standard with documented purity and traceability.

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.
