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)-3-(3,4-Dihydroxybenzylidene)dihydrofuran-2(3H)-one.
(E)-3-(3,4-Dihydroxybenzylidene)dihydrofuran-2(3H)-one (CAS 102271-71-6) is a high-purity analytical reference standard with the molecular formula C11H10O4 and a molecular weight of 206.19 g/mol.
The molecular framework of (E)-3-(3,4-Dihydroxybenzylidene)dihydrofuran-2(3H)-one (C11H10O4) 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 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.
CATO manufactures (E)-3-(3,4-Dihydroxybenzylidene)dihydrofuran-2(3H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
