Chemical Structure
Description
As a certified reference material (CRM), 3,6-Dibromo-2,7-diiodophenanthrene-9,10-dione 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.
CATO supplies 3,6-Dibromo-2,7-diiodophenanthrene-9,10-dione (CAS 887127-69-7), a certified reference material (molecular formula C14H4Br2I2O2, MW 617.80 g/mol) for analytical method development and quality control.
3,6-Dibromo-2,7-diiodophenanthrene-9,10-dione (C14H4Br2I2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine/iodine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
