Description
As a certified reference material (CRM), 6-Bromo-2,3,3-trimethyl-3H-indole 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.
6-Bromo-2,3,3-trimethyl-3H-indole (CAS 145306-21-4) is a high-purity analytical reference standard with the molecular formula C11H12BrN and a molecular weight of 238.12 g/mol.
6-Bromo-2,3,3-trimethyl-3H-indole (C11H12BrN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
