Chemical Structure
Description
The molecular framework of 7-bromo-4-fluoro-1,3-benzoxazole (C7H11BrFNO) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine/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.
CATO supplies 7-bromo-4-fluoro-1,3-benzoxazole (CAS 1934713-13-9), a certified reference material (molecular formula C7H11BrFNO, MW 224.07 g/mol) for analytical method development and quality control.
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), 7-bromo-4-fluoro-1,3-benzoxazole 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.
