Chemical Structure

4,4'-(((2,5-Dibromo-1,4-phenylene)bis(methylene))bis(oxy))dibenzaldehyde CAS 2304559-58-6 chemical structure

Description

CATO supplies 4,4'-(((2,5-Dibromo-1,4-phenylene)bis(methylene))bis(oxy))dibenzaldehyde (CAS 2304559-58-6), a certified reference material (molecular formula C22H16Br2O4, MW 504.17 g/mol) for analytical method development and quality control.

Based on its molecular formula C22H16Br2O4, 4,4'-(((2,5-Dibromo-1,4-phenylene)bis(methylene))bis(oxy))dibenzaldehyde contains a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 504.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), 4,4'-(((2,5-Dibromo-1,4-phenylene)bis(methylene))bis(oxy))dibenzaldehyde 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.
