Description
As a certified reference material (CRM), 1,6-Dichloro-7-methyl-3-(trifluoromethyl)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.
1,6-Dichloro-7-methyl-3-(trifluoromethyl)naphthalene (CAS 537033-71-9), molecular formula C12H7Cl2F3 and molecular weight 279.09 g/mol, is a CATO reference standard with documented purity and traceability.
1,6-Dichloro-7-methyl-3-(trifluoromethyl)naphthalene (C12H7Cl2F3) contains fluorine/chlorine 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. 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.
