Chemical Structure
Description
4-(2,5-Difluorobenzyl)piperidine hydrochloride (CAS 149986-59-4), molecular formula C12H15F2NHCl and molecular weight 247.71 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H15F2NHCl, 4-(2,5-Difluorobenzyl)piperidine hydrochloride contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 247.71 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
