(3aR,8bS)-2-(1,8-Naphthyridin-2-yl)-4,8b-dihydro-3aH-indeno[1,2-d][1,3]oxazole (CAS 2757082-48-5) is a high-purity analytical reference standard with the molecular formula C18H13N3O and a molecular weight of 287.32 g/mol.
The molecular framework of (3aR,8bS)-2-(1,8-Naphthyridin-2-yl)-4,8b-dihydro-3aH-indeno[1,2-d][1,3]oxazole (C18H13N3O) 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.
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.
