(R)-2-((R)-2-((tert-Butoxycarbonyl)amino)-3-(1H-indol-3-yl)propanamido)-3-(1H-indol-3-yl)propanoic acid (CAS 160623-01-8), molecular formula C27H30N4O5 and molecular weight 490.55 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (R)-2-((R)-2-((tert-Butoxycarbonyl)amino)-3-(1H-indol-3-yl)propanamido)-3-(1H-indol-3-yl)propanoic acid (C27H30N4O5) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 490.55 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).
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.
