Description
As a certified reference material (CRM), 2-(2-(Trifluoromethyl)phenyl)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.
2-(2-(Trifluoromethyl)phenyl)naphthalene (CAS 1261732-75-5) is a high-purity analytical reference standard with the molecular formula C17H11F3 and a molecular weight of 272.26 g/mol.
Owing to fluorine substitution, a polycyclic aromatic system, 2-(2-(Trifluoromethyl)phenyl)naphthalene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 272.26 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.
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.
