Chemical Structure

2,6-Dibromonaphthalene-1,5-diol CAS 84-59-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,6-Dibromonaphthalene-1,5-diol.

2,6-Dibromonaphthalene-1,5-diol (CAS 84-59-3) is a high-purity analytical reference standard with the molecular formula C10H6Br2O2 and a molecular weight of 317.96 g/mol.

2,6-Dibromonaphthalene-1,5-diol (C10H6Br2O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, bromine 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-Dibromonaphthalene-1,5-diol 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.
