1,1'-(Bromomethylene)dinaphthalene CAS 5467-20-9

Description

The occurrence of 1,1'-(Bromomethylene)dinaphthalene is closely related to bromine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,1'-(Bromomethylene)dinaphthalene (CAS 5467-20-9) is a high-purity analytical reference standard with the molecular formula C21H15Br and a molecular weight of 347.25 g/mol.

Based on its molecular formula C21H15Br, 1,1'-(Bromomethylene)dinaphthalene contains bromine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 347.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.

As a certified reference material (CRM), 1,1'-(Bromomethylene)dinaphthalene 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.
