Description
As a certified reference material (CRM), 2-((2-Nitro-4-(trifluoromethyl)phenyl)thio)aniline meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
2-((2-Nitro-4-(trifluoromethyl)phenyl)thio)aniline (CAS 322-71-4), molecular formula C13H9F3N2O2S and molecular weight 314.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-((2-Nitro-4-(trifluoromethyl)phenyl)thio)aniline (C13H9F3N2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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.
