Description
CATO manufactures 1,2,3,4-Tetrachloronaphthalene 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.
1,2,3,4-Tetrachloronaphthalene (CAS 20020-02-4), molecular formula C10H4Cl4 and molecular weight 265.95 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H4Cl4, 1,2,3,4-Tetrachloronaphthalene contains chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 265.95 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
