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 (S)-2,4-bis((tert-butoxycarbonyl)amino)butanoic acid.
(S)-2,4-bis((tert-butoxycarbonyl)amino)butanoic acid (CAS 34404-27-8), molecular formula C14H26N2O6 and molecular weight 318.37 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, (S)-2,4-bis((tert-butoxycarbonyl)amino)butanoic acid is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 318.37 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.
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.
