1,2-thiazol-4-amine dihydrochloride CAS 1955519-82-0

Description

Compared with other compounds in its class, the molecular weight of 136.60 g/mol gives 1,2-thiazol-4-amine dihydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1,2-thiazol-4-amine dihydrochloride (CAS 1955519-82-0) is a high-purity analytical reference standard with the molecular formula C3H4N2SHCl and a molecular weight of 136.60 g/mol.

Based on its molecular formula C3H4N2SHCl, 1,2-thiazol-4-amine dihydrochloride contains a nitrile group, sulfur-containing functionality, chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 136.60 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
