Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
methyl 6-bromo-1H-benzimidazole-2-carboxylate (CAS 885280-00-2), molecular formula C9H15BrN2O2 and molecular weight 263.13 g/mol, is a CATO reference standard with documented purity and traceability.
methyl 6-bromo-1H-benzimidazole-2-carboxylate (C9H15BrN2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, 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. 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), methyl 6-bromo-1H-benzimidazole-2-carboxylate 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.
