(S)-2-Methyl-1,1'-binaphthyl CAS 118018-45-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-2-Methyl-1,1'-binaphthyl.

CATO supplies (S)-2-Methyl-1,1'-binaphthyl (CAS 118018-45-4), a certified reference material (molecular formula C21H16, MW 268.35 g/mol) for analytical method development and quality control.

(S)-2-Methyl-1,1'-binaphthyl (C21H16) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

As a certified reference material (CRM), (S)-2-Methyl-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.
