Global N,N-Diethyl-2-propyneammonium Sulfate Market Strategic Research Report

Scope of the Report

The global N,N-Diethyl-2-propyneammonium Sulfate market size is predicted to grow from US$ 7.48 million in 2025 to US$ 10.14 million in 2032; it is expected to grow at a CAGR of 4.5% from 2026 to 2032.

In 2025, the global sales volume of N,N-Diethyl-2-propyneammonium Sulfate is estimated at approximately 860 tons, with the mainstream ex-factory average price at around USD 8.9/kg. The gross margin of major manufacturer is approximately 28%–42%.

N,N-Diethyl-2-propyneammonium Sulfate is an alkynyl amine nickel plating intermediate, commonly abbreviated as TC-DEP, with CAS No. 84779-61-3. The product is usually supplied as an approximately 50% aqueous solution, typically appearing as a colorless to pale yellow transparent liquid. It is readily soluble in water and is mainly used in nickel plating additive systems such as bright nickel plating and semi-bright nickel plating. Its molecular structure contains both an alkynyl group and a diethylamine salt structure, enabling it to influence cathodic deposition behavior during nickel plating and improve coating brightness, leveling performance, and low-current-density area coverage.

Its upstream raw material mainly includes N,N-diethylpropargylamine, sulfuric acid, solvent, water treatment auxiliary, stabilizer and packaging material. Key production requirements include salt formation reaction control, active content stability, color control, impurity control and batch-to-batch consistency. Downstream, it is mainly used in nickel plating processing fields such as decorative hardware electroplating, automotive part electroplating, electronic connector electroplating and mechanical part electroplating, especially in process systems with high requirements for coating brightness, leveling ability, low-current-density throwing power and appearance consistency.

Global key N,N-Diethyl-2-propyneammonium Sulfate players cover Wuhan Jadechem New Materials, Wuhan Pinestone Technology, Wuhan Bright Chemical, Hainan Zhongxin Chemical, Shanghai Theorem Chemical Technology, etc.
