Description
As a certified reference material (CRM), 5-Bromo-2-methyl-2,3-dihydro-1H-inden-1-one 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.
5-Bromo-2-methyl-2,3-dihydro-1H-inden-1-one (CAS 104107-22-4) is a high-purity analytical reference standard with the molecular formula C10H9BrO and a molecular weight of 225.08 g/mol.
Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 5-Bromo-2-methyl-2,3-dihydro-1H-inden-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 225.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
