Bis(4-tert-butylphenyl)iodonium 2-trifluoromethylbenzenesulfonate CAS 229325-98-8 (This line of electronic-grade chemicals can be customized to meet your specific metal impurity specifications; we welcome custom orders.)

1. Core application: A photoacid generator (PAG) specifically designed for i-line, KrF, and ArF lithography resists, belonging to the diaryliodonium salt class of cationic PAGs. Upon exposure, it efficiently decomposes to generate trifluoromethylbenzenesulfonic acid, exhibiting high quantum yield, strong acidity, and low acid diffusion—making it a key photosensitive component in chemically amplified resists.

2. Suitable for semiconductor wafer lithography, advanced packaging, and micro‑pattern fabrication of MEMS devices in 65 nm to 250 nm process nodes, it can enhance the photosensitivity and development contrast of photoresists while reducing pattern edge roughness.

3. Cationic photoinitiators for UV-curable coatings, inks, and adhesives, particularly well-suited for photocuring reactions involving fluorinated resins and epoxy systems; they offer rapid curing and leave no solvent residues.

4. Photoresist additives, used to modulate the photoresist’s photosensitivity, acid diffusion rate, and development performance, thereby optimizing the lithography process window.

Specifications: Fluorine spectrum purity ≥99%, individual metal ion content <50 ppb, acid value 0.

Store in a cool, dark place, tightly sealed.

Jiangsu Juming Chemical Technology Co., Ltd. was established in November 2017 and has been deeply engaged in the chemical industry for many years. The company is headquartered in Jiangyin City, Jiangsu Province. Its production bases are located in Shandong, Hebei, Henan, and Hubei Provinces in China. The laboratory is equipped with four gas chromatographs and eight liquid chromatographs. The company primarily manufactures and markets fine chemical products, including electronic-grade chemicals, water treatment agents, UV absorbers, and agrochemical and pharmaceutical intermediates, which are widely sold in Europe, the United States, Japan, South Korea, and other countries and regions. Key products include 5-methylbenzotriazole at an annual capacity of 2,000 tons, 1,2,3-benzotriazole (BTA) at 3,000 tons per year, benzotriazole sodium salt (BTA-Na) at 2,000 tons per year, methylbenzotriazole (TTA) at 3,000 tons per year, methylbenzotriazole sodium salt (TTA-Na) at 2,000 tons per year, carbohydrazide (carbonyl hydrazine) at 2,000 tons per year, and benzophenone (BP) at 2,000 tons per year. These products are extensively used in water treatment, as chemical intermediates, in agrochemicals and pharmaceuticals, as UV absorbers, in fertilizers, in dyeing and printing, as flame retardants in fire‑proof materials, and in the production of magnesium salts. The company holds ISO 9001 certification, SGS certification, and CMA testing accreditation.
Since its establishment, the company has earned the recognition of numerous clients and built a strong reputation through word of mouth. The team at Juming will work in close collaboration with partners across society to achieve shared success!
