Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Fmoc-(S)-2-amino-4-(2-pyridyl)butyric acid.
CATO supplies Fmoc-(S)-2-amino-4-(2-pyridyl)butyric acid (CAS 1260601-08-8), a certified reference material (molecular formula C24H22N2O4, MW 402.44 g/mol) for analytical method development and quality control.
The molecular framework of Fmoc-(S)-2-amino-4-(2-pyridyl)butyric acid (C24H22N2O4) 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.
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.
