Description
As a certified reference material (CRM), Ethyl 3-bromo-6,6-difluoro-4,5,6,7-tetrahydro-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.
Ethyl 3-bromo-6,6-difluoro-4,5,6,7-tetrahydro-1H-indole-2-carboxylate (CAS 1956380-53-2) is a high-purity analytical reference standard with the molecular formula C11H12BrF2NO2 and a molecular weight of 308.12 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, Ethyl 3-bromo-6,6-difluoro-4,5,6,7-tetrahydro-1H-indole-2-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 308.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
