Description

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.

(2S,5S,8S,11S,14S,17S,20S,23S,26S,29S)-8-(2-Amino-2-oxoethyl)-2-(3-amino-3-oxopropyl)-11,20,29-tris(4-aminobutyl)-26-(3-guanidinopropyl)-17-isopropyl-5,14-dimethyl-23-(2-(methylthio)ethyl)-4,7,10,13,16,19,22,25,28,31-decaoxo-3,6,9,12,15,18,21,24,27,30-decaazatetratetracontan-1-oic acid (CAS 1423381-07-0) is a high-purity analytical reference standard with the molecular formula C63H118N18O14S and a molecular weight of 1383.79 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, (2S,5S,8S,11S,14S,17S,20S,23S,26S,29S)-8-(2-Amino-2-oxoethyl)-2-(3-amino-3-oxopropyl)-11,20,29-tris(4-aminobutyl)-26-(3-guanidinopropyl)-17-isopropyl-5,14-dimethyl-23-(2-(methylthio)ethyl)-4,7,10,13,16,19,22,25,28,31-decaoxo-3,6,9,12,15,18,21,24,27,30-decaazatetratetracontan-1-oic acid is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1383.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
