Chemical Structure
Description
The occurrence of (2E)-1,4-Bis(4-methoxyphenyl)but-2-ene-1,4-dione is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies (2E)-1,4-Bis(4-methoxyphenyl)but-2-ene-1,4-dione (CAS 15331-49-4), a certified reference material (molecular formula C18H16O4, MW 296.32 g/mol) for analytical method development and quality control.
The molecular framework of (2E)-1,4-Bis(4-methoxyphenyl)but-2-ene-1,4-dione (C18H16O4) 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).
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), (2E)-1,4-Bis(4-methoxyphenyl)but-2-ene-1,4-dione 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.
