Chemical Structure
Description
Naphthalene-2,7-dicarbonyl dichloride (CAS 17989-82-1), molecular formula C12H6Cl2O2 and molecular weight 253.08 g/mol, is a CATO reference standard with documented purity and traceability.
Naphthalene-2,7-dicarbonyl dichloride (C12H6Cl2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring 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).
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), Naphthalene-2,7-dicarbonyl dichloride 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.
