1-(5-Amino-1,2,4-thiadiazol-3-yl)propan-2-one CAS 912770-70-8

Description

The molecular framework of 1-(5-Amino-1,2,4-thiadiazol-3-yl)propan-2-one (C5H7N3OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

1-(5-Amino-1,2,4-thiadiazol-3-yl)propan-2-one (CAS 912770-70-8) is a high-purity analytical reference standard with the molecular formula C5H7N3OS and a molecular weight of 157.19 g/mol.

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.
