Description

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.

(R)​-2,​2',​3,​3'-​Tetrahydro-​6,​6'-​bis(2,​4,​6-​trimethylphenyl)​-1,​1'-​spirobi[1H-​indene]​-​7,​7'-​diol (CAS 1435948-37-0) is a high-purity analytical reference standard with the molecular formula C35H36O2 and a molecular weight of 488.66 g/mol.

Based on its molecular formula C35H36O2, (R)​-2,​2',​3,​3'-​Tetrahydro-​6,​6'-​bis(2,​4,​6-​trimethylphenyl)​-1,​1'-​spirobi[1H-​indene]​-​7,​7'-​diol contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 488.66 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
