2-(3-chlorophenyl)-4-piperazin-1-yl-6-(trifluoromethyl)pyrimidine (CAS 1443978-68-4), molecular formula C15H14ClF3N4 and molecular weight 342.75 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(3-chlorophenyl)-4-piperazin-1-yl-6-(trifluoromethyl)pyrimidine (C15H14ClF3N4) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
