Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Ethyl 6-bromo-7-methyl-1H-indole-2-carboxylate (CAS 459817-63-1), molecular formula C12H12BrNO2 and molecular weight 282.13 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H12BrNO2, Ethyl 6-bromo-7-methyl-1H-indole-2-carboxylate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 282.13 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), Ethyl 6-bromo-7-methyl-1H-indole-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.
