Chemical Structure
Description
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.
n-(4-Bromo-3-methylphenyl)-2-(piperidin-1-yl)acetamide (CAS 196082-32-3), molecular formula C14H19BrN2O and molecular weight 311.22 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of n-(4-Bromo-3-methylphenyl)-2-(piperidin-1-yl)acetamide (C14H19BrN2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
