Compared with other compounds in its class, the molecular weight of 299.99 g/mol gives 2-bromo-7-(bromomethyl)naphthalene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-bromo-7-(bromomethyl)naphthalene (CAS 841259-75-4), a certified reference material (molecular formula C11H8Br2, MW 299.99 g/mol) for analytical method development and quality control.
Owing to bromine substitution, an aromatic ring system, 2-bromo-7-(bromomethyl)naphthalene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 299.99 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 2-bromo-7-(bromomethyl)naphthalene 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.
