Chemical Structure
Description
(S)-3,3'-Bis(triphenylsilyl)-1,1'-bi-2-naphthol (C56H42O2Si2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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.
(S)-3,3'-Bis(triphenylsilyl)-1,1'-bi-2-naphthol (CAS 111795-33-6), molecular formula C56H42O2Si2 and molecular weight 803.10 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), (S)-3,3'-Bis(triphenylsilyl)-1,1'-bi-2-naphthol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
