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 2-[(tert-butoxycarbonyl)amino]-3-phenylbutanoic acid.
2-[(tert-butoxycarbonyl)amino]-3-phenylbutanoic acid (CAS 630424-76-9), molecular formula C15H21NO4 and molecular weight 279.33 g/mol, is a CATO reference standard with documented purity and traceability.
2-[(tert-butoxycarbonyl)amino]-3-phenylbutanoic acid (C15H21NO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
