DIPHENYLIODONIUM PERFLUORO-1- CAS 194999-82-1 (This line of electronic-grade chemicals can be customized to meet your specifications for metallic impurity levels; we welcome custom orders.) 

1. Core application: Proton‑generating acid generators (PAGs) for ArF, EUV, and electron‑beam lithography resists, which belong to the quaternary ammonium salt class of cationic PAGs. Upon exposure, they decompose to generate perfluorobutanesulfonic acid, exhibiting exceptionally strong acidity, high quantum yield, and excellent thermal stability, making them the key photosensitive components in advanced chemically amplified resists.

2. ArF immersion photoresists for 7nm–65nm logic chips and DRAM/NAND flash memory, as well as EUV extreme ultraviolet photoresists, enhance photoresist photosensitivity and pattern resolution.

3. Photoinitiator for cationic UV-curable coatings and inks, used in the photocuring of fluorinated resins;

4. Photosensitizers for photochromic materials and photocatalytic systems

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 advanced analytical instruments, including four gas chromatographs and eight liquid chromatographs. The company primarily manufactures and markets fine chemical products such as 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, chemical intermediates, agrochemicals, pharmaceuticals, UV absorbers, fertilizers, textile dyeing, flame retardants for fire‑proof materials, and 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 colleagues across society to achieve shared success! 
 

We have a professional export team and our chemicals are exported to European、Asia and American countries. We can do OEM and ODM services. We have a chemicals develop team that develops and designs new chemicals every year.
