(2r,3s)-3-(acetyloxy)-1,4-bis(acetylsulfanyl)butan-2-yl acetate 4214-85-1 KST-1A4773 (CAS 4214-85-1) is a high-purity analytical reference standard with the molecular formula C5H6N4O3 and a molecular weight of 170.13 g/mol.

The molecular framework of (2r,3s)-3-(acetyloxy)-1,4-bis(acetylsulfanyl)butan-2-yl acetate 4214-85-1 KST-1A4773 (C5H6N4O3) is characterized by an amino-acid-derived structure, 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.
