CATO supplies (3R)-3-[[(9H-Fluoren-9-ylmethoxy)carbonyl]amino]butanoic acid (CAS 201864-71-3), a certified reference material (molecular formula C19H19NO4, MW 325.36 g/mol) for analytical method development and quality control.
The molecular framework of (3R)-3-[[(9H-Fluoren-9-ylmethoxy)carbonyl]amino]butanoic acid (C19H19NO4) 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.
