CATO supplies (S)-2-Acetamido-N-(1-(((S)-1-(((S)-1-amino-2-methyl-1-oxo-3-phenylpropan-2-yl)amino)-5-guanidino-1-oxopentan-2-yl)amino)-2-methyl-1-oxopropan-2-yl)-5-guanidinopentanamide (CAS 1006388-38-0), a certified reference material (molecular formula C28H47N11O5, MW 617.74 g/mol) for analytical method development and quality control.
Structurally, (S)-2-Acetamido-N-(1-(((S)-1-(((S)-1-amino-2-methyl-1-oxo-3-phenylpropan-2-yl)amino)-5-guanidino-1-oxopentan-2-yl)amino)-2-methyl-1-oxopropan-2-yl)-5-guanidinopentanamide (C28H47N11O5) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 617.74 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.
