Name: Eastman Di-p-toluenesulfonamide Potassium Salt
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Eastman Di-p-toluenesulfonamide Potassium Salt

Highly effective potassium-based sulfonamide catalyst for selective condensation and cyclization reactions.
Enhanced thermal stability compared to sodium or ammonium analogues, supporting high-temperature process conditions.
Excellent solubility in polar aprotic solvents such as DMF, DMSO, and NMP—facilitating homogeneous reaction systems.
Low volatility and non-hygroscopic nature ensure consistent handling, storage, and dosing accuracy.
Meets stringent purity requirements for pharmaceutical intermediate synthesis and fine chemical manufacturing.

Typical Applications Of Eastman Di-p-toluenesulfonamide Potassium Salt

Catalyst in the synthesis of heterocyclic compounds, including benzimidazoles and triazoles.
Key promoter in Knoevenagel condensations for active methylene compound functionalization.
Enabling reagent in solid-phase peptide coupling and protected amino acid activation.
Stabilizing agent and co-catalyst in palladium-catalyzed cross-coupling reactions (e.g., Suzuki and Heck variants).
