Chemical Structure
Description
As a certified reference material (CRM), 5-Bromo-2-(thiophen-2-yl)benzo[d]oxazole 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.
CATO supplies 5-Bromo-2-(thiophen-2-yl)benzo[d]oxazole (CAS 915923-09-0), a certified reference material (molecular formula C11H6BrNOS, MW 280.14 g/mol) for analytical method development and quality control.
The molecular framework of 5-Bromo-2-(thiophen-2-yl)benzo[d]oxazole (C11H6BrNOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
