Chemical Structure

3-[(2E)-3-(2,4-Dichlorophenyl)prop-2-enoyl]-4-hydroxy-6-methyl-2H-pyran-2-one CAS 1141393-10-3 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 3-[(2E)-3-(2,4-Dichlorophenyl)prop-2-enoyl]-4-hydroxy-6-methyl-2H-pyran-2-one.

CATO supplies 3-[(2E)-3-(2,4-Dichlorophenyl)prop-2-enoyl]-4-hydroxy-6-methyl-2H-pyran-2-one (CAS 1141393-10-3), a certified reference material (molecular formula C15H10Cl2O4, MW 325.14 g/mol) for analytical method development and quality control.

The molecular framework of 3-[(2E)-3-(2,4-Dichlorophenyl)prop-2-enoyl]-4-hydroxy-6-methyl-2H-pyran-2-one (C15H10Cl2O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. 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 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), 3-[(2E)-3-(2,4-Dichlorophenyl)prop-2-enoyl]-4-hydroxy-6-methyl-2H-pyran-2-one 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.
