(R)-1,1'-Binaphthyl-2,2'-dicarboxylic acid CAS 80703-23-7 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 (R)-1,1'-Binaphthyl-2,2'-dicarboxylic acid.

(R)-1,1'-Binaphthyl-2,2'-dicarboxylic acid (CAS 80703-23-7) is a high-purity analytical reference standard with the molecular formula C22H14O4 and a molecular weight of 342.34 g/mol.

Based on its molecular formula C22H14O4, (R)-1,1'-Binaphthyl-2,2'-dicarboxylic acid contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 342.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
