(S)-2-Acetamido-N-(2-(((S)-1-amino-1-oxopropan-2-yl)amino)-2-oxoethyl)-3-(1H-indol-3-yl)propanamide (CAS 71525-89-8), molecular formula C18H23N5O4 and molecular weight 373.41 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (S)-2-Acetamido-N-(2-(((S)-1-amino-1-oxopropan-2-yl)amino)-2-oxoethyl)-3-(1H-indol-3-yl)propanamide (C18H23N5O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures (S)-2-Acetamido-N-(2-(((S)-1-amino-1-oxopropan-2-yl)amino)-2-oxoethyl)-3-(1H-indol-3-yl)propanamide 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.
