2-{4-[2-nitro-4-(trifluoromethyl)phenyl]piperazin-1-yl}ethyl 3-(trifluoromethyl)benzoate (CAS 338748-62-2), molecular formula C21H19F6N3O4 and molecular weight 491.38 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-{4-[2-nitro-4-(trifluoromethyl)phenyl]piperazin-1-yl}ethyl 3-(trifluoromethyl)benzoate (C21H19F6N3O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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. 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.
