Chemical Structure
Description
1-(2-Methylthiazol-4-yl)ethan-1-one hydrobromide (CAS 317377-32-5), molecular formula C6H7NOSHBr and molecular weight 222.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-(2-Methylthiazol-4-yl)ethan-1-one hydrobromide (C6H7NOSHBr) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-(2-Methylthiazol-4-yl)ethan-1-one hydrobromide 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.
