Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4-Bromo-2-(piperidin-1-ylmethyl)pyridine (CAS 956593-44-5), molecular formula C11H15BrN2 and molecular weight 255.15 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Bromo-2-(piperidin-1-ylmethyl)pyridine (C11H15BrN2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, 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.
