Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Benzylidene-2-(3-fluorophenyl)oxazol-5(4H)-one (CAS 89242-22-8) is a high-purity analytical reference standard with the molecular formula C16H10FNO2 and a molecular weight of 267.25 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 4-Benzylidene-2-(3-fluorophenyl)oxazol-5(4H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 267.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 4-Benzylidene-2-(3-fluorophenyl)oxazol-5(4H)-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.
