Description
As a certified reference material (CRM), (S)-2,2'-Dimethyl-1,1'-binaphthyl 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.
CATO supplies (S)-2,2'-Dimethyl-1,1'-binaphthyl (CAS 32587-64-7), a certified reference material (molecular formula C22H18, MW 282.38 g/mol) for analytical method development and quality control.
Structurally, (S)-2,2'-Dimethyl-1,1'-binaphthyl (C22H18) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 282.38 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
