Description

Compared with other compounds in its class, the molecular weight of 270.78 g/mol gives 4-(5-Ethyl-2-methoxyphenyl)thiazol-2-amine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4-(5-Ethyl-2-methoxyphenyl)thiazol-2-amine hydrochloride (CAS 1177321-15-1), molecular formula C12H14N2OSHCl and molecular weight 270.78 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C12H14N2OSHCl, 4-(5-Ethyl-2-methoxyphenyl)thiazol-2-amine hydrochloride contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 270.78 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.
