Description
CATO manufactures 2-(Difluoromethoxy)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.
2-(Difluoromethoxy)naphthalene (CAS 712-79-8), molecular formula C11H8F2O and molecular weight 194.18 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(Difluoromethoxy)naphthalene (C11H8F2O) is characterized by a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
