(S)-N-(2-(((S)-1-Amino-3-(1H-indol-3-yl)-1-oxopropan-2-yl)amino)-2-oxoethyl)-1-((S)-2-aminopropanoyl)pyrrolidine-2-carboxamide acetate (CAS 144110-40-7), molecular formula C21H28N6O4C2H4O2 and molecular weight 488.54 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (S)-N-(2-(((S)-1-Amino-3-(1H-indol-3-yl)-1-oxopropan-2-yl)amino)-2-oxoethyl)-1-((S)-2-aminopropanoyl)pyrrolidine-2-carboxamide acetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 488.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), (S)-N-(2-(((S)-1-Amino-3-(1H-indol-3-yl)-1-oxopropan-2-yl)amino)-2-oxoethyl)-1-((S)-2-aminopropanoyl)pyrrolidine-2-carboxamide acetate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
