Chemical Structure
Description
Oxyfluorfen (CAS 42874-03-3), molecular formula C15H11ClF3NO4 and molecular weight 361.70 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Oxyfluorfen (C15H11ClF3NO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
