Chemical Structure

(E)-4-(4-Hydroxyphenyl)-4-oxobut-2-enoic acid CAS 86690-79-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-4-(4-Hydroxyphenyl)-4-oxobut-2-enoic acid.

CATO supplies (E)-4-(4-Hydroxyphenyl)-4-oxobut-2-enoic acid (CAS 86690-79-1), a certified reference material (molecular formula C10H8O4, MW 192.17 g/mol) for analytical method development and quality control.

The molecular framework of (E)-4-(4-Hydroxyphenyl)-4-oxobut-2-enoic acid (C10H8O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).

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-Hydroxyphenyl)-4-oxobut-2-enoic 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.
