Chemical Structure
Description
CATO supplies 2-Bromo-5-iodothiazole (CAS 108306-63-4), a certified reference material (molecular formula C3HBrINS, MW 289.92 g/mol) for analytical method development and quality control.
2-Bromo-5-iodothiazole (C3HBrINS) contains a nitrile group, sulfur-containing functionality, bromine/iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
As a certified reference material (CRM), 2-Bromo-5-iodothiazole 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.
