Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 251.68 g/mol gives 4-(3-Chloro-4-fluorophenoxy)-3-methylphenylamine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-(3-Chloro-4-fluorophenoxy)-3-methylphenylamine (CAS 946741-91-9), molecular formula C13H11ClFNO and molecular weight 251.68 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(3-Chloro-4-fluorophenoxy)-3-methylphenylamine (C13H11ClFNO) 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4-(3-Chloro-4-fluorophenoxy)-3-methylphenylamine 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.
