Chemical Structure
Description
Structurally, (4S,5S)-2,2-Dimethyl-α4,α4,α5,α5-tetra-2-naphthalenyl-1,3-dioxolane-4,5-dimethanol (C47H38O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 29.0, corresponding to approximately 29 ring(s) or double-bond equivalent(s). With a molecular weight of 666.80 g/mol, it falls into the 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.
CATO supplies (4S,5S)-2,2-Dimethyl-α4,α4,α5,α5-tetra-2-naphthalenyl-1,3-dioxolane-4,5-dimethanol (CAS 137365-16-3), a certified reference material (molecular formula C47H38O4, MW 666.80 g/mol) for analytical method development and quality control.
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.
