16-(Adamantane-1-carbonyl)-11,15-dioxa-16-azatetracyclo[8.7.0.0^{2,7}.0^{13,17}]heptadeca-1,3,5,7,9-pentaene (CAS 339098-61-2) is a high-purity analytical reference standard with the molecular formula C25H27NO3 and a molecular weight of 389.49 g/mol.
The molecular framework of 16-(Adamantane-1-carbonyl)-11,15-dioxa-16-azatetracyclo[8.7.0.0^{2,7}.0^{13,17}]heptadeca-1,3,5,7,9-pentaene (C25H27NO3) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
