Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Bromomethyl-isonicotinic acid methyl ester hydrobromide (CAS 1956366-21-4), molecular formula C8H8BrNO2HBr and molecular weight 310.97 g/mol, is a CATO reference standard with documented purity and traceability.
2-Bromomethyl-isonicotinic acid methyl ester hydrobromide (C8H8BrNO2HBr) contains a nitrogen-containing heterocyclic scaffold, an amide 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).
As a certified reference material (CRM), 2-Bromomethyl-isonicotinic acid methyl ester hydrobromide 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.
