Description
As a certified reference material (CRM), 3-Bromo-4-(propan-2-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.
3-Bromo-4-(propan-2-yl)pyridine (CAS 90731-96-7), molecular formula C8H10BrN and molecular weight 200.08 g/mol, is a CATO reference standard with documented purity and traceability.
3-Bromo-4-(propan-2-yl)pyridine (C8H10BrN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
