Description
CATO manufactures (S)-tert-butyl 3-((S)-2-(((benzyloxy)carbonyl)amino)propanamido)-5-bromo-4-oxopentanoate 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.
(S)-tert-butyl 3-((S)-2-(((benzyloxy)carbonyl)amino)propanamido)-5-bromo-4-oxopentanoate (CAS 868565-55-3) is a high-purity analytical reference standard with the molecular formula C20H27BrN2O6 and a molecular weight of 471.34 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, (S)-tert-butyl 3-((S)-2-(((benzyloxy)carbonyl)amino)propanamido)-5-bromo-4-oxopentanoate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 471.34 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.
