Chemical Structure
Description
The molecular framework of Tert-butyl 4-(2-(4-chlorophenyl)-2-oxoethyl)piperazine-1-carboxylate (C17H23ClN2O3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
Tert-butyl 4-(2-(4-chlorophenyl)-2-oxoethyl)piperazine-1-carboxylate (CAS 1146080-70-7) is a high-purity analytical reference standard with the molecular formula C17H23ClN2O3 and a molecular weight of 338.83 g/mol.
