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-Fluorophenyl)-2-oxobut-3-enoic acid.
CATO supplies (E)-4-(4-Fluorophenyl)-2-oxobut-3-enoic acid (CAS 515824-21-2), a certified reference material (molecular formula C10H7FO3, MW 194.16 g/mol) for analytical method development and quality control.
Structurally, (E)-4-(4-Fluorophenyl)-2-oxobut-3-enoic acid (C10H7FO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 194.16 g/mol, it falls into the medium-molecular-weight range. 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), (E)-4-(4-Fluorophenyl)-2-oxobut-3-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.
