2,6-Naphthalenedicarboxylic diacid dichloride CAS 2351-36-2

Description

Compared with other compounds in its class, the molecular weight of 253.08 g/mol gives 2,6-Naphthalenedicarboxylic diacid dichloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2,6-Naphthalenedicarboxylic diacid dichloride (CAS 2351-36-2), molecular formula C12H6Cl2O2 and molecular weight 253.08 g/mol, is a CATO reference standard with documented purity and traceability.

2,6-Naphthalenedicarboxylic diacid 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), 2,6-Naphthalenedicarboxylic diacid 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.
