Chemical Structure
Description
The occurrence of Fmoc-Lys(palmitoyl-Glu-OtBu)-OH is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Fmoc-Lys(palmitoyl-Glu-OtBu)-OH (CAS 1491158-62-3), a certified reference material (molecular formula C46H69N3O8, MW 792.06 g/mol) for analytical method development and quality control.
The molecular framework of Fmoc-Lys(palmitoyl-Glu-OtBu)-OH (C46H69N3O8) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
