Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(Bromomethyl)-7-ethylbenzo[d]oxazole (CAS 1803837-57-1), molecular formula C10H10BrNO and molecular weight 240.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(Bromomethyl)-7-ethylbenzo[d]oxazole (C10H10BrNO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), 2-(Bromomethyl)-7-ethylbenzo[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.
