(2Z)-3-Ethyl-2-[(4H-1,2,4-triazol-4-yl)imino]-1,3-thiazolidin-4-one CAS 5102-46-5

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.

(2Z)-3-Ethyl-2-[(4H-1,2,4-triazol-4-yl)imino]-1,3-thiazolidin-4-one (CAS 5102-46-5) is a high-purity analytical reference standard with the molecular formula C7H9N5OS and a molecular weight of 211.24 g/mol.

Based on its molecular formula C7H9N5OS, (2Z)-3-Ethyl-2-[(4H-1,2,4-triazol-4-yl)imino]-1,3-thiazolidin-4-one contains an amide group, sulfur-containing functionality, 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 211.24 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.
