2-Propenoic acid, 2-methyl-, 2-[(hexahydro-2,2-dioxido-3,5-methanocyclopent[d]-1,2-oxathiol-6-yl)oxy]-2-oxoethyl ester CAS 1135824-87-1 (This line of electronic-grade chemicals can be customized to meet your specific metal impurity specifications; we welcome custom orders.) 

1. Core application: A copolymer monomer serving as the main resin in 193 nm ArF photoresists, featuring a tricyclic sulfonate lactone structure that provides acid‑trapping and buffering capabilities, thereby suppressing lateral diffusion of photo‑generated acids, significantly reducing line‑width roughness (LWR), and enhancing pattern resolution and process window.

2. A 248 nm KrF deep‑UV photoresist‑compatible monomer that enhances thick‑resist development uniformity and etch resistance, suitable for power semiconductor and memory chip manufacturing processes.

3. Functional monomers for EUV extreme ultraviolet and electron-beam lithography; sulfur‑based additives enhance the EUV photon absorption cross-section, enabling the fabrication of ultra‑fine patterns at 7 nm and below.

4. A top‑coat water‑resistant coating resin monomer for 193 nm immersion lithography, which balances the film’s polarity and optimizes development‑and‑strip performance.

5. Synthetic monomers for low‑dielectric‑constant (Low‑k) interlayer dielectric resins and specialized plasma‑resistant coatings

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. 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 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! 
 

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.
