Description
As a certified reference material (CRM), 5-bromo-2-(2-methylpropane-2-sulfonyl)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.
CATO supplies 5-bromo-2-(2-methylpropane-2-sulfonyl)pyridine (CAS 123792-44-9), a certified reference material (molecular formula C9H12BrNO2S, MW 278.17 g/mol) for analytical method development and quality control.
5-bromo-2-(2-methylpropane-2-sulfonyl)pyridine (C9H12BrNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
