5-Aminothiazole-2(3H)-thione CAS 6294-51-5

Description

The occurrence of 5-Aminothiazole-2(3H)-thione is closely related to a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Aminothiazole-2(3H)-thione (CAS 6294-51-5) is a high-purity analytical reference standard with the molecular formula C3H4N2S2 and a molecular weight of 132.21 g/mol.

5-Aminothiazole-2(3H)-thione (C3H4N2S2) contains a nitrile group, sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

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.
