Chemical Structure
Description
Ethyl 2-Aminothiazole-4-acetate Hydrochloride (CAS 76629-17-9) is a high-purity analytical reference standard with the molecular formula C7H10N2O2SHCl and a molecular weight of 222.69 g/mol.
The molecular framework of Ethyl 2-Aminothiazole-4-acetate Hydrochloride (C7H10N2O2SHCl) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. 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).
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.
As a certified reference material (CRM), Ethyl 2-Aminothiazole-4-acetate Hydrochloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
