Chemical Structure
Description
The molecular framework of (R)-Lipoamido-PEG4-acid (C19H35NO7S2) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
(R)-Lipoamido-PEG4-acid (CAS 1334172-69-8), molecular formula C19H35NO7S2 and molecular weight 453.61 g/mol, is a CATO reference standard with documented purity and traceability.
