9-Bromo-2,3-dimethylanthracene (CAS 27111-62-2), molecular formula C16H13Br and molecular weight 285.18 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to bromine substitution, a polycyclic aromatic system, 9-Bromo-2,3-dimethylanthracene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 285.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 9-Bromo-2,3-dimethylanthracene 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.
