Chemical Structure
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.
(3aR,3’aR,4R,4’R,6R,6’R,7aS,7’aS)-3a,3’a,5,5,5’,5’-Hexamethyldodecahydro-2,2’-bi[4,6-methanobenzo[d][1,3,2]dioxaborole] (CAS 230299-17-9) is a high-purity analytical reference standard with the molecular formula C20H32B2O4 and a molecular weight of 358.09 g/mol.
The molecular framework of (3aR,3’aR,4R,4’R,6R,6’R,7aS,7’aS)-3a,3’a,5,5,5’,5’-Hexamethyldodecahydro-2,2’-bi[4,6-methanobenzo[d][1,3,2]dioxaborole] (C20H32B2O4) is characterized by a steroid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
