Description
(S)-2-(((2R,3R,4R,5R,6R)-3-Acetamido-2-(((1R,2R,3S,5R)-3-ethyl-5-((38-oxo-2,5,8,11,14,17,20,23,26,29,32,35-dodecaoxa-39-azahentetracontan-41-yl)carbamoyl)-2-(((2S,3S,4R,5S,6S)-3,4,5-trihydroxy-6-methyltetrahydro-2H-pyran-2-yl)oxy)cyclohexyl)oxy)-5-hydroxy (CAS 1983970-12-2), molecular formula C60H109N3O27 and molecular weight 1304.51 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (S)-2-(((2R,3R,4R,5R,6R)-3-Acetamido-2-(((1R,2R,3S,5R)-3-ethyl-5-((38-oxo-2,5,8,11,14,17,20,23,26,29,32,35-dodecaoxa-39-azahentetracontan-41-yl)carbamoyl)-2-(((2S,3S,4R,5S,6S)-3,4,5-trihydroxy-6-methyltetrahydro-2H-pyran-2-yl)oxy)cyclohexyl)oxy)-5-hydroxy (C60H109N3O27) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 1304.51 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.
