Description
(S)-3-Azido-2-(Fmoc-amino)propionic acid 684270-46-0 Fmoc-3-azido-L-alanine Fmoc-|A-azido-Ala-OH (CAS 684270-46-0), molecular formula C18H28N4O4 and molecular weight 364.44 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-3-Azido-2-(Fmoc-amino)propionic acid 684270-46-0 Fmoc-3-azido-L-alanine Fmoc-|A-azido-Ala-OH (C18H28N4O4) is characterized by a flavonoid core, 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.
