2-Propenoic acid, 2-methyl-, 5-[2,2,2-trifluoro-1-hydroxy-1-( trifluoromethyl)ethyl]bicyclo[2. 2.1]hept-2-yl ester CAS 676460-86-9 (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 photoresist, the copolymerizable monomer serves as the main resin component; its rigid bicyclic [2.2.1] heptane (norbornane) backbone imparts excellent dry‑etch resistance and thermal stability, while the bis‑trifluoromethyl hydroxyl groups confer both alkali solubility and hydrophobicity, thereby balancing the photoresist’s etch resistance and development performance.

2. A top-layer water‑repellent coating resin monomer for 193 nm immersion lithography, which increases the water contact angle of the film and suppresses the leaching of photoresist components into pure water.

3. Nanoscale imprint lithography photoresist monomers that reduce curing shrinkage and enhance release properties, used for the fabrication of micro- and nano-optical structures;

4. Synthetic monomers for specialty fluorine‑containing weather‑resistant coatings and low‑surface‑energy self‑cleaning coatings

Specification: Purity ≥ 99.5%, single metal < 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. 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 (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 textile 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!
