Chemical Structure
Description
The molecular framework of <I>N</I>-[2-(Fmoc-amino)-ethyl]-Gly-<I>O</I>-tBu hydrochloride (C23H40N2O4HCl) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
<I>N</I>-[2-(Fmoc-amino)-ethyl]-Gly-<I>O</I>-tBu hydrochloride (CAS 169396-88-7), molecular formula C23H40N2O4HCl and molecular weight 445.04 g/mol, is a CATO reference standard with documented purity and traceability.
