Chemical Structure
Description
1-(2-Bromo-4-(difluoromethyl)phenyl)-4-methylpiperidine (C13H16BrF2N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1-(2-Bromo-4-(difluoromethyl)phenyl)-4-methylpiperidine (CAS 1704073-17-5) is a high-purity analytical reference standard with the molecular formula C13H16BrF2N and a molecular weight of 304.17 g/mol.
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.
As a certified reference material (CRM), 1-(2-Bromo-4-(difluoromethyl)phenyl)-4-methylpiperidine 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.
