Chemical Structure
Description
3,5-dimethyl-1-[4-(trifluoromethyl)phenyl]piperazine (CAS 1503801-78-2) is a high-purity analytical reference standard with the molecular formula C13H17F3N2 and a molecular weight of 258.28 g/mol.
Based on its molecular formula C13H17F3N2, 3,5-dimethyl-1-[4-(trifluoromethyl)phenyl]piperazine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 258.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
