5-[3,3,3-Trifluoro-2-hydroxy-2-(trifluoromethyl)propyl]bicyclo[2.2.1]hept-2-yl 2-methyl-2-propenoate CAS 617711-94-1 (This line of electronic-grade chemicals can be customized to meet your specifications for metal impurity levels; we welcome custom orders.)

1. Core application: In 193 nm ArF dry and immersion lithography, the main resin copolymer monomer features a bicyclic alicyclic structure that enhances the resin’s etching resistance, while a long-chain fluorinated hydroxyl group optimizes the alkali dissolution rate and hydrophobicity, thereby improving the photoresist’s development contrast and line-edge roughness.

2. A top‑coat water‑resistant coating resin monomer for 193 nm immersion lithography, which enhances the hydrophobicity of the film layer, reduces water‑induced etching defects, and optimizes development and stripping performance.

3. KrF photoresist‑modified monomers, enhancing the etch resistance and pattern uniformity of thick resists;

4. Synthetic monomers for low-dielectric-constant resins and fluorine-containing coatings with chemical resistance

Specification: Purity ≥ 99.5%, single metal impurities < 50 ppb

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 bases located in Shandong, Hebei, Henan, and Hubei Provinces. Its 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 (2,000 tons per year), 1,2,3-benzotriazole (BTA) (3,000 tons per year), benzotriazole sodium salt (BTA-Na) (2,000 tons per year), methylbenzotriazole (TTA) (3,000 tons per year), methylbenzotriazole sodium salt (TTA-Na) (2,000 tons per year), carbohydrazide (carbonyl hydrazine) (2,000 tons per year), and benzophenone (BP) (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 colleagues across society to achieve shared success!
