2-Chloromethylstyrene (pure meta isomer), CAS 22570-84-9

Applications: Used as a core polymerization monomer for the synthesis of high-performance negative-tone photoresist resins (such as E-beam electron-beam lithography resists) and advanced packaging dielectric materials, as well as for the production of homogeneous ion-exchange membranes, ultrapure water resins, and chelating resins.

The product is highly prone to autopolymerization; therefore, a specific ppm-level inhibitor (such as TBC, tert-butylcatechol) is typically added at the factory to ensure stability. Strict cold-chain transportation and low-temperature storage (usually between 2°C and 9°C or lower) are essential. The primary purpose of the cold chain is to prevent polymerization, allowing the inhibitor to remain effective and prolong the product’s shelf life.

Jiangsu Juming Chemical Technology Co., Ltd. was established in November 2017 and is an integrated enterprise encompassing R&D, production, trade, and diversified services. The company is headquartered in Jiangyin City, Jiangsu Province, with production bases located in Shandong, Hebei, Henan, and Hubei Provinces in China. It currently employs 1,000 workers and operates a state-of-the-art laboratory equipped with four gas chromatographs and eight liquid chromatographs. The company primarily manufactures and markets electronic-grade chemicals, water treatment agents, UV absorbers, agrochemical and pharmaceutical intermediates, and other fine chemical products, which are widely sold in Europe, the United States, Japan, South Korea, and numerous other countries and regions. Its core products include 5-methylbenzotriazole, with an annual output of 2,000 metric tons, and 1,2,3-benzotriazole (BTA), with an annual output of
Annual production capacities include 3,000 tonnes of [unspecified product], 2,000 tonnes per year of sodium benzotriazole (BTA-Na), 3,000 tonnes per year of methylbenzotriazole (TTA), 2,000 tonnes per year of sodium methylbenzotriazole (TTA-Na), 2,000 tonnes per year of carbohydrazide (carbonyl hydrazine), and 2,000 tonnes per year of benzophenone (BP). These products are widely used in water treatment, as chemical intermediates, in the pesticide and pharmaceutical industries, as UV absorbers, in fertilizers, in printing and dyeing, as flame retardants for fireproof materials, and in the production of magnesium salts. We hold ISO 9001 certification, SGS certification, and CMA testing accreditation, and we are recognized as a contract-abiding and trustworthy enterprise.
Since its establishment, the company has earned unanimous recognition from numerous clients and enjoys a stellar reputation that continues to grow by word of mouth. The team at Juming is committed to forging sincere partnerships with colleagues across society to achieve shared success and brilliance!
