🔬 Common Scientific Applications
⚗️ Acylation catalyst (nucleophilic): Accelerates acylation of alcohols, phenols, and amines with anhydrides or acyl chlorides via acyl-pyridinium intermediates.
🧪 Steglich esterification additive: With DCC/EDC, promotes mild, high-yield ester formation at room temperature; useful for sensitive substrates.
🧬 Peptide/amide couplings (auxiliary): Boosts rates/selectivity in difficult amide bond formations; lowers epimerization vs. harsher activators.
🧷 Transesterification & acyl transfer: Catalyzes exchange reactions and migration steps in complex molecule and protecting-group workflows.
🍬 Carbohydrate chemistry: Efficiently acylates hindered/secondary alcohols; regioselective protection of polyols.
🧱 Polymer & materials synthesis: Esterification/crosslinking catalyst in preparing polyesters, dendrimers, and functional coatings.
🎯 Chemoselective acylations: Favors O-acylation over N-acylation in many systems; tuning via solvent/base and temperature.
🧰 Method development/QC: Benchmark catalyst for comparing acylation conditions, kinetics, and impurity profiles.
R&D use only. Corrosive/irritant; handle dry and minimize exposure. Verify compatibility with acid chlorides/anhydrides and consult the SDS/CoA for your lot.
