5-[(propan-2-yl)amino]-1,3,4-thiadiazole-2-thiol CAS 750608-54-9

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.

5-[(propan-2-yl)amino]-1,3,4-thiadiazole-2-thiol (CAS 750608-54-9), molecular formula C5H9N3S2 and molecular weight 175.28 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-[(propan-2-yl)amino]-1,3,4-thiadiazole-2-thiol (C5H9N3S2) is characterized by a nitrile group, sulfur-containing functionality. 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).

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.
