Chemical Structure
Description
The molecular framework of 1-(Naphthalen-2-ylsulfonyl)indoline (C18H15NO2S) is characterized by a steroid core, an amide group, a sulfone 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.
1-(Naphthalen-2-ylsulfonyl)indoline (CAS 326007-87-8), molecular formula C18H15NO2S and molecular weight 309.38 g/mol, is a CATO reference standard with documented purity and traceability.
