(2S,3R)-(R)-1-((3S,6S,9S,12S,18R,21S,22R)-21-Acetamido-18-benzyl-22-isopropyl-3-((R)-1-methoxyethyl)-4,9,10,12,16-pentamethyl-15-methylene-2,5,8,11,14,17,20-heptaoxo-1,19-dioxa-4,7,10,13,16-pentaazacyclodocosan-6-yl)-2-methylpropyl 3-hydroxy-4-methyl-2-propionamidopentanoate (CAS 107530-18-7) is a high-purity analytical reference standard with the molecular formula C49H75N7O15 and a molecular weight of 1002.16 g/mol.
Based on its molecular formula C49H75N7O15, (2S,3R)-(R)-1-((3S,6S,9S,12S,18R,21S,22R)-21-Acetamido-18-benzyl-22-isopropyl-3-((R)-1-methoxyethyl)-4,9,10,12,16-pentamethyl-15-methylene-2,5,8,11,14,17,20-heptaoxo-1,19-dioxa-4,7,10,13,16-pentaazacyclodocosan-6-yl)-2-methylpropyl 3-hydroxy-4-methyl-2-propionamidopentanoate contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 1002.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
