Compared with other compounds in its class, the molecular weight of 239.08 g/mol gives 1-Bromomethyl-7-fluoronaphthalene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Bromomethyl-7-fluoronaphthalene (CAS 70631-50-4), molecular formula C11H8BrF and molecular weight 239.08 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine/bromine substitution, an aromatic ring system, 1-Bromomethyl-7-fluoronaphthalene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 239.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures 1-Bromomethyl-7-fluoronaphthalene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
