Chemical Structure

2-(Trifluoromethyl)naphthalene CAS 581-90-8 chemical structure

Description

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.

2-(Trifluoromethyl)naphthalene (CAS 581-90-8) is a high-purity analytical reference standard with the molecular formula C11H7F3 and a molecular weight of 196.17 g/mol.

2-(Trifluoromethyl)naphthalene (C11H7F3) contains fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures 2-(Trifluoromethyl)naphthalene 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.
