Description
As a certified reference material (CRM), 1,2-Dibromo-4-cyclopropoxybenzene 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.
1,2-Dibromo-4-cyclopropoxybenzene (CAS 1243409-73-5) is a high-purity analytical reference standard with the molecular formula C9H8Br2O and a molecular weight of 291.97 g/mol.
1,2-Dibromo-4-cyclopropoxybenzene (C9H8Br2O) 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
