Chemical Structure
Description
CATO supplies (E)-4,4’-(Ethene-1,2-diyl)dibenzoic Acid (CAS 74299-91-5), a certified reference material (molecular formula C16H12O4, MW 268.26 g/mol) for analytical method development and quality control.
The molecular framework of (E)-4,4’-(Ethene-1,2-diyl)dibenzoic Acid (C16H12O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
As a certified reference material (CRM), (E)-4,4’-(Ethene-1,2-diyl)dibenzoic Acid 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.
