Chemical Structure
Description
(Z)-5-((E)-4-Hydroxybut-2-en-1-ylidene)-3-((E)-3-hydroxyprop-1-en-1-yl)furan-2(5H)-one (CAS 132074-82-9) is a high-purity analytical reference standard with the molecular formula C11H12O4 and a molecular weight of 208.21 g/mol.
(Z)-5-((E)-4-Hydroxybut-2-en-1-ylidene)-3-((E)-3-hydroxyprop-1-en-1-yl)furan-2(5H)-one (C11H12O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
