Chemical Structure
Description
As a certified reference material (CRM), 1-(Dimethyl-1,3-thiazol-5-yl)ethan-1-one 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.
1-(Dimethyl-1,3-thiazol-5-yl)ethan-1-one hydrochloride (CAS 88323-87-9), molecular formula C7H9NOSHCl and molecular weight 191.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(Dimethyl-1,3-thiazol-5-yl)ethan-1-one hydrochloride (C7H9NOSHCl) is characterized by an amide group, sulfur-containing functionality, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
