Chemical Structure
Description
2-Bromo-4-methoxy-1,3-dimethylbenzene (C9H11BrO) contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
2-Bromo-4-methoxy-1,3-dimethylbenzene (CAS 23453-90-9) is a high-purity analytical reference standard with the molecular formula C9H11BrO and a molecular weight of 215.09 g/mol.
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), 2-Bromo-4-methoxy-1,3-dimethylbenzene 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.
