1-(6-Methylthiazolo[3,2-b][1,2,4]triazol-5-yl)ethyl thiophene-2-carboxylate CAS 338401-76-6

Description

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.

1-(6-Methylthiazolo[3,2-b][1,2,4]triazol-5-yl)ethyl thiophene-2-carboxylate (CAS 338401-76-6) is a high-purity analytical reference standard with the molecular formula C12H11N3O2S2 and a molecular weight of 293.36 g/mol.

Based on its molecular formula C12H11N3O2S2, 1-(6-Methylthiazolo[3,2-b][1,2,4]triazol-5-yl)ethyl thiophene-2-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 293.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
