Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 348.29 g/mol gives 1,1＇-Binaphthyl-2,2＇-diyl hydrogenphosphate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,1＇-Binaphthyl-2,2＇-diyl hydrogenphosphate (CAS 35193-63-6) is a high-purity analytical reference standard with the molecular formula C20H13O4P and a molecular weight of 348.29 g/mol.
Structurally, 1,1＇-Binaphthyl-2,2＇-diyl hydrogenphosphate (C20H13O4P) contains a flavonoid core, a phosphate ester group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.5, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 348.29 g/mol, it falls into the moderately-high-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.
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.
