Benzocyclobutene CAS 694-87-1 (This line of electronic-grade chemicals can be customized to meet your specific metal impurity specifications; we welcome custom orders.)

Applications: advanced semiconductor packaging, 5G/6G high-frequency communications, next-generation OLED displays, and specialty high-performance resins.

Specification: Electronic grade, purity 99.8%

Benzocyclobutene (CAS 694-87-1) is primarily used as a monomer for high-performance electronic materials and as an intermediate in organic synthesis. In the context of electronic packaging and dielectric materials, when heated to approximately 200°C, its four-membered ring undergoes ring-opening to generate highly reactive intermediates, which can either self-polymerize or participate in Diels–Alder reactions with dienophiles, yielding thermosetting polymers. The resulting resins exhibit a low dielectric constant (~2.6), low moisture absorption, a high glass transition temperature (>350°C), and excellent film smoothness.

Widely used in: interlayer dielectrics (ILD) in multilayer interconnect structures, passivation and packaging materials for advanced chips and microelectronic devices, and modified resins for high-frequency, high-speed circuit substrates (often copolymerized with siloxanes or fluorine to enhance performance).

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 across China in Shandong, Hebei, Henan, and Hubei Provinces. Its laboratory is equipped with advanced 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, chemical intermediates, agrochemicals, pharmaceuticals, UV absorbers, fertilizers, textile dyeing and printing, flame retardants for fire‑proof materials, and 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.
