Description

The occurrence of (2R,5R,8R,11R,14R)-11-((1H-Indol-3-yl)methyl)-14-amino-2,5-dibenzyl-8-methyl-4,7,10,13-tetraoxo-15-phenyl-3,6,9,12-tetraazapentadecan-1-oic acid 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.

(2R,5R,8R,11R,14R)-11-((1H-Indol-3-yl)methyl)-14-amino-2,5-dibenzyl-8-methyl-4,7,10,13-tetraoxo-15-phenyl-3,6,9,12-tetraazapentadecan-1-oic acid (CAS 644997-29-5), molecular formula C41H44N6O6 and molecular weight 716.82 g/mol, is a CATO reference standard with documented purity and traceability.

(2R,5R,8R,11R,14R)-11-((1H-Indol-3-yl)methyl)-14-amino-2,5-dibenzyl-8-methyl-4,7,10,13-tetraoxo-15-phenyl-3,6,9,12-tetraazapentadecan-1-oic acid (C41H44N6O6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
