Chemical Structure
Description
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.
(3aS,3a'S,8aR,8a'R)-2,2'-(Propane-2,2-diyl)bis(8,8a-dihydro-3aH-indeno[1,2-d]oxazole) (CAS 175166-51-5) is a high-purity analytical reference standard with the molecular formula C23H22N2O2 and a molecular weight of 358.43 g/mol.
The molecular framework of (3aS,3a'S,8aR,8a'R)-2,2'-(Propane-2,2-diyl)bis(8,8a-dihydro-3aH-indeno[1,2-d]oxazole) (C23H22N2O2) is characterized by a steroid core, an amide group, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
