Chemical Structure
Description
CATO manufactures 2,6-Dichloronaphthalene 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.
2,6-Dichloronaphthalene (CAS 2065-70-5), molecular formula C10H6Cl2 and molecular weight 197.06 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,6-Dichloronaphthalene (C10H6Cl2) is characterized by chlorine 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.
