Chemical Structure
Description
The molecular framework of Ethyl 2-(6,7-dihydro-5H-thiazolo[3,2-a]pyrimidin-3-yl)acetate hydrochloride (C10H14N2O2SHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Ethyl 2-(6,7-dihydro-5H-thiazolo[3,2-a]pyrimidin-3-yl)acetate hydrochloride (CAS 76629-22-6) is a high-purity analytical reference standard with the molecular formula C10H14N2O2SHCl and a molecular weight of 262.75 g/mol.
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.
