Description
CATO manufactures (E)-2-(4-fluorophenoxy)benzaldehyde oxime 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.
(E)-2-(4-fluorophenoxy)benzaldehyde oxime (CAS 449778-79-4), molecular formula C13H10FNO2 and molecular weight 231.22 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, (E)-2-(4-fluorophenoxy)benzaldehyde oxime is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
