1H-Benz[de]isoquinoline-1,3(2 H)-dione,2-[[(pentafluoroethyl) sulfonyl]oxy]- CAS 850468-75-6 (This line of electronic-grade chemicals can be customized to meet your specific metal impurity specifications; we welcome custom orders.)

1. Core application: Photoinitiators (PAGs) for KrF, ArF, and EUV lithography resists, belonging to the naphthalimide sulfonate class of PAGs. Upon exposure, they generate perfluoroalkyl sulfonic acids, exhibiting high acid strength, high photosensitivity, and low diffusion, making them well-suited for chemically amplified resist systems.

2. ArF photoresists for 14–65 nm processes and EUV photoresists for sub-7 nm processes, enhancing pattern resolution and line-width roughness control;

3. Photoinitiators for UV-curable systems, used in precision optical coatings and micro/nano‑scale lithographic resists;

4. Photoresist additives used to modulate the acid diffusion rate and develop contrast of the photoresist.

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, with production facilities located across China in Shandong, Hebei, Henan, and Hubei Provinces. Its laboratory is equipped with state-of-the-art 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 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 hydrazide) 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!
