Chemical Structure
Description
(1S,2S)-1,2-Di(naphthalen-1-yl)ethane-1,2-diol (C22H18O2) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
(1S,2S)-1,2-Di(naphthalen-1-yl)ethane-1,2-diol (CAS 229184-99-0), molecular formula C22H18O2 and molecular weight 314.38 g/mol, is a CATO reference standard with documented purity and traceability.
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 (1S,2S)-1,2-Di(naphthalen-1-yl)ethane-1,2-diol 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.
