Chemical Structure
Description
As a certified reference material (CRM), (S)-2,2-Bis(methoxymethoxy)-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.
(S)-2,2-Bis(methoxymethoxy)-1,1-binaphthyl (CAS 74292-20-9), molecular formula C24H22O4 and molecular weight 374.43 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-2,2-Bis(methoxymethoxy)-1,1-binaphthyl (C24H22O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
