Structurally, (2S)-2-[[(2R,3R)-3-[(2S)-1-[(3R,4S,5S)-4-[[(2S)-2-[[(2S)-2-[[4-[[(2S)-2-[[(2S)-2-[3-[2-[2-[2-[2-[[4-(2-azatricyclo[10.4.0.0⁴⁹]hexadeca-1(16),4,6,8,12,14-hexaen-10-yn-2-yl)-4-oxo-butanoyl]amino]ethoxy]ethoxy]ethoxy]ethoxy]propanoylamino]-3-methyl-butanoyl]amino]-5-ureido-pentanoyl]amino]phenyl]methoxycarbonyl-methyl-amino]-3-methyl-butanoyl]amino]-3-methyl-butanoyl]-methyl-amino]-3-methoxy-5-methyl-heptanoyl]pyrrolidin-2-yl]-3-methoxy-2-methyl-propanoyl]amino]-3-phenyl-propanoic acid (C88H126N12O20) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 32.0, corresponding to approximately 32 ring(s) or double-bond equivalent(s). With a molecular weight of 1672.01 g/mol, it falls into the 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.
