Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 180.61 g/mol gives 1-CHloro-4-fluoronaphthalene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-CHloro-4-fluoronaphthalene (CAS 315-51-5) is a high-purity analytical reference standard with the molecular formula C10H6ClF and a molecular weight of 180.61 g/mol.
Owing to fluorine/chlorine substitution, an aromatic ring system, 1-CHloro-4-fluoronaphthalene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 180.61 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
