The occurrence of N-((2S,5S,8S,11S,14S,17S,20S)-1,24-Diamino-17-(4-aminobutyl)-2-benzyl-11-(3-guanidinopropyl)-14-(hydroxymethyl)-5-isobutyl-8-methyl-1,4,7,10,13,16,19-heptaoxo-3,6,9,12,15,18-hexaazatetracosan-20-yl)palmitamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies N-((2S,5S,8S,11S,14S,17S,20S)-1,24-Diamino-17-(4-aminobutyl)-2-benzyl-11-(3-guanidinopropyl)-14-(hydroxymethyl)-5-isobutyl-8-methyl-1,4,7,10,13,16,19-heptaoxo-3,6,9,12,15,18-hexaazatetracosan-20-yl)palmitamide (CAS 371131-16-7), a certified reference material (molecular formula C55H99N13O9, MW 1086.46 g/mol) for analytical method development and quality control.
The molecular framework of N-((2S,5S,8S,11S,14S,17S,20S)-1,24-Diamino-17-(4-aminobutyl)-2-benzyl-11-(3-guanidinopropyl)-14-(hydroxymethyl)-5-isobutyl-8-methyl-1,4,7,10,13,16,19-heptaoxo-3,6,9,12,15,18-hexaazatetracosan-20-yl)palmitamide (C55H99N13O9) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
