Chemical Structure
Description
The occurrence of 2,3-Dibromonaphthalene is closely related to bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,3-Dibromonaphthalene (CAS 13214-70-5), a certified reference material (molecular formula C10H6Br2, MW 285.96 g/mol) for analytical method development and quality control.
Based on its molecular formula C10H6Br2, 2,3-Dibromonaphthalene contains bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 285.96 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 2,3-Dibromonaphthalene 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.
