Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 192.03 g/mol gives 5-Bromothiazole-4-carbaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 5-Bromothiazole-4-carbaldehyde (CAS 934346-19-7), a certified reference material (molecular formula C4H2BrNOS, MW 192.03 g/mol) for analytical method development and quality control.
The molecular framework of 5-Bromothiazole-4-carbaldehyde (C4H2BrNOS) 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.
CATO manufactures 5-Bromothiazole-4-carbaldehyde 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.
