Chemical Structure
Description
The molecular framework of 3-(2-Hydroxyethyl)thiazol-3-ium bromide (C5H8NOSBr) 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.
3-(2-Hydroxyethyl)thiazol-3-ium bromide (CAS 103768-99-6) is a high-purity analytical reference standard with the molecular formula C5H8NOSBr and a molecular weight of 210.09 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.
CATO manufactures 3-(2-Hydroxyethyl)thiazol-3-ium bromide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
