【Introduce Us】Beijing Wenhaiyang Perylenes Chemistry, specializing in manufacturing perylene family products, is a professional company in R&D of chemiluminescence dye. From the 1990s, Wenhaiyang company has synthetized and developed full-color fluorescent dye for chemiluminescence. In order to break the blockade of foreign countries’ patent, Wenhaiyang company has devoted to the R&D of perylene family products from year 2000 and has gained great achievements. With the large-scale synthetizing of 1,6,7,12 - tetrachloroperylene tetracarboxylic acid dianhydride (CAS#:156028-26-1), because of high-quality and large output of our products, we have made business cooperation with many domestic and international companies. We also offer high grade and low-cost raw materials to the units of domestic scientific research at the R&D of substituent perylene derivative. Realizing industrialized and batch production of substitute perylene derivative, especially, our company made an important development in 8C and 18C substitute for the synthetizing of 1,6,7,12 - tetra -t -butylphenoxy - N - N' - dioctyl-perylene - 3,4,9,10 - tetracarboxylic dianhydride (CAS#:872005-48-6), which can substitute for high-cost Lumaogen-F Red 300. Cooperating with institutions of higher education, we succeeded in developing perylene family infrared chemiluminescence dye which has a high-stable performance, which bring ua a breakthrough progress. As the continuous development of electronic industry, special dyeing techniques and organic solar cell technology, perylene chemical technology have enjoyed more and more attention and favor from people in this field. Wenhaiyang company will try her best to offer best services for widespread R&D institutions and customers. Moreover, we will continually improve our technical level and rich products series.
