Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 100.14 g/mol gives 2-Aminothiazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-Aminothiazole (CAS 96-50-4), a certified reference material (molecular formula C3H4N2S, MW 100.14 g/mol) for analytical method development and quality control.
Structurally, 2-Aminothiazole (C3H4N2S) contains a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 100.14 g/mol, it falls into the low-molecular-weight range. 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.
