5-Bromo-4-methyl-2-(4-methyl-1-piperidinyl)-pyridine CAS 1219964-45-0

Description

Compared with other compounds in its class, the molecular weight of 269.18 g/mol gives 5-Bromo-4-methyl-2-(4-methyl-1-piperidinyl)-pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Bromo-4-methyl-2-(4-methyl-1-piperidinyl)-pyridine (CAS 1219964-45-0), molecular formula C12H17BrN2 and molecular weight 269.18 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Bromo-4-methyl-2-(4-methyl-1-piperidinyl)-pyridine (C12H17BrN2) 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
