Chemical Structure
Description
As a certified reference material (CRM), 2,4-Dibromo-6-Chlorophenol 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.
2,4-Dibromo-6-Chlorophenol (CAS 4526-56-1) is a high-purity analytical reference standard with the molecular formula C6H3Br2ClO and a molecular weight of 286.35 g/mol.
2,4-Dibromo-6-Chlorophenol (C6H3Br2ClO) 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
