2,2'-Dimethyl-1,1'-binaphthalene CAS 60536-98-3 chemical structure

Description

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.

2,2'-Dimethyl-1,1'-binaphthalene (CAS 60536-98-3), molecular formula C22H18 and molecular weight 282.38 g/mol, is a CATO reference standard with documented purity and traceability.

2,2'-Dimethyl-1,1'-binaphthalene (C22H18) contains a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

CATO manufactures 2,2'-Dimethyl-1,1'-binaphthalene 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.
