The occurrence of 2,4-Dichloro-6-[[3-(Trifluoromethyl)Phenyl]Amino]Benzene-1,3,5-Tricarbonitrile is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2,4-Dichloro-6-[[3-(Trifluoromethyl)Phenyl]Amino]Benzene-1,3,5-Tricarbonitrile (CAS 35728-02-0), molecular formula C16H5Cl2F3N4 and molecular weight 381.14 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,4-Dichloro-6-[[3-(Trifluoromethyl)Phenyl]Amino]Benzene-1,3,5-Tricarbonitrile (C16H5Cl2F3N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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 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.
