Chemical Structure
Description
(2S)-2-Amino-5-(((2R)-1-((carboxymethyl)amino)-3-((2-((4-(hydroxyhydroarsoryl)phenyl)amino)-2-oxoethyl)thio)-1-oxopropan-2-yl)amino)-5-oxopentanoic acid (CAS 334756-34-2) is a high-purity analytical reference standard with the molecular formula C18H25AsN4O9S and a molecular weight of 548.40 g/mol.
Structurally, (2S)-2-Amino-5-(((2R)-1-((carboxymethyl)amino)-3-((2-((4-(hydroxyhydroarsoryl)phenyl)amino)-2-oxoethyl)thio)-1-oxopropan-2-yl)amino)-5-oxopentanoic acid (C18H25AsN4O9S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.5, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 548.40 g/mol, it falls into the moderately-high-molecular-weight range. 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.
