CATO supplies (R)-2-((tert-butoxycarbonyl)amino)-4-cyclopropylbutanoic acid (CAS 2349893-77-0), a certified reference material (molecular formula C12H21NO4, MW 243.30 g/mol) for analytical method development and quality control.
(R)-2-((tert-butoxycarbonyl)amino)-4-cyclopropylbutanoic acid (C12H21NO4) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
