Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Bromo-3-methyl-2-(3-methylpiperidin-1-yl)pyridine (CAS 1219967-98-2), molecular formula C12H17BrN2 and molecular weight 269.18 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 5-Bromo-3-methyl-2-(3-methylpiperidin-1-yl)pyridine is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 269.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 5-Bromo-3-methyl-2-(3-methylpiperidin-1-yl)pyridine 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.
