Description
CATO manufactures (2S)-2-amino-4-(benzyloxycarbonylamino)butanoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
(2S)-2-amino-4-(benzyloxycarbonylamino)butanoic acid (CAS 2130-77-0), molecular formula C12H22N2O4 and molecular weight 258.31 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, (2S)-2-amino-4-(benzyloxycarbonylamino)butanoic acid is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 258.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
