Chemical Structure
Description
The occurrence of Ethyl 5-(2-bromobenzyl)-1,2,4-oxadiazole-3-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Ethyl 5-(2-bromobenzyl)-1,2,4-oxadiazole-3-carboxylate (CAS 1216696-40-0), a certified reference material (molecular formula C12H11BrN2O3, MW 311.13 g/mol) for analytical method development and quality control.
Ethyl 5-(2-bromobenzyl)-1,2,4-oxadiazole-3-carboxylate (C12H11BrN2O3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures Ethyl 5-(2-bromobenzyl)-1,2,4-oxadiazole-3-carboxylate 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.
