This polyether-functionalized dioxopyrrolidinyl ester features a 47-atom aliphatic chain terminated by a reactive ester group, enabling efficient coupling to carboxylic acid-containing biomolecules. The extended polyether backbone imparts high solubility in polar solvents and enhances stability under aqueous conditions, making it suitable for conjugation workflows requiring prolonged shelf life and minimal aggregation.
2,5-Dioxopyrrolidin-1-yl 2,5,8,11,14,17,20,23,26,29,32,35,38,41,44,47-hexadecaoxapentacontan-50-oate serves as a robust, bench-stable ester activating agent for carboxylic acids in peptide coupling and polymer functionalization. Its extended polyether chain enhances solubility in polar aprotic solvents while maintaining high reactivity under standard conditions. The N-hydroxypyrrolidone leaving group facilitates clean reaction progress with minimal racemization, enabling efficient formation of esters and amides across diverse substrates.
