CAS 439694-03-8 : Ultra-high refractive index monomer (This line of electronic-grade chemicals can be customized to meet your specific metal impurity specifications; we accept custom orders.) 

English name: 1,3,5-Tris[(2-thioxo-1,3-oxathiolan-5-yl)methyl]-1,3,5-triazine-2,4,6(1H,3H,5H)-trione

Technical Analysis: This molecular design is highly forward-looking. It combines a triazine core with three sulfur-containing heterocycles (thiones). - oxathiolane). The sulfur atom exhibits a very high molar refractivity ( Molar Refraction ). 

Applications: By introducing a large amount of sulfur, this monomer can be polymerized to produce a material with a refractive index ( RI ) Extremely high ( >1.7 ) optical resin. In smartphone lenses, microlens arrays, and Virtual Reality In display devices, high-refractive-index materials enable the same light-concentrating performance with thinner lenses, making them a key material for lightweight optical systems.  。

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 manufacture 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!  

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.
