On activating a carboxylic acid it forms an HODhbt active ester that suppresses azlactone-driven racemization, giving amide bonds with high stereochemical retention without protecting serine, threonine or tyrosine side chains, for solution- and solid-phase synthesis and cyclization.

With a tertiary amine base it converts carboxylic acids in situ to reactive acyl fluorides, which acylate amines to amides with low racemization, coupling even hindered acids and electron-deficient amines in solution- and solid-phase peptide synthesis.

Coupled to a carboxylic acid with a carbodiimide it gives a stable, isolable pentafluorophenyl (OPfp) active ester that acylates amines cleanly, a workhorse for solution- and solid-phase peptide synthesis and bioconjugation. It also serves as a hydrogen-bond-donor organocatalyst. Supplied by NorrChemica with DDP shipping.

Its succinimidyl groups convert carboxylic acids into N-succinimidyl (NHS) esters and activate alcohols as NHS carbonates, which react with amines to form amides and carbamates. Widely used for peptide coupling, immobilization on solid supports and bioconjugation.
