4-(4-Chloro-3-fluorophenyl)-4-oxobutanenitrile (CAS 1248664-88-1), molecular formula C10H7ClFNO and molecular weight 211.62 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(4-Chloro-3-fluorophenyl)-4-oxobutanenitrile (C10H7ClFNO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
