Description
As a certified reference material (CRM), 2,6-Dibromo-4-chloro-benzaldehyde 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.
2,6-Dibromo-4-chloro-benzaldehyde (CAS 2247038-89-5) is a high-purity analytical reference standard with the molecular formula C7H3Br2ClO and a molecular weight of 298.36 g/mol.
2,6-Dibromo-4-chloro-benzaldehyde (C7H3Br2ClO) contains a hydroxyl group, an ether linkage, chlorine/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.
