Chemical Structure

Trans-Nonachlor CAS 39765-80-5 chemical structure

Description

Trans-Nonachlor (CAS 39765-80-5), molecular formula C10H5Cl9 and molecular weight 444.22 g/mol, is a CATO reference standard with documented purity and traceability.

Trans-Nonachlor (C10H5Cl9) contains 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures Trans-Nonachlor 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.
