Today, we will introduce an important heat-resistant polymer monomer, 1,5-diaminonaphthalene, alias: 1,5-naphthalene diamine; CAS No.: 2243-62-1, the purity of HPLC is more than 99%. It is used as the intermediate of organic synthesis, the polymerizing monomer of heat-resistant polymers such as polyimide and polyamide, 1,5-diaminonaphthalene, CAS No.: 2243-62-1, the purity of which is above 99%, 5-diaminonaphthalene (5-diaminonaphthalene) leaves are used to synthesize various fine chemical products, such as pigments, dyes, rubber additives, resins and photosensitive materials, 25kg packaging. The annual output of 1,5-diaminonaphthalene (1,5-naphthalene diamine) is 300 tons. The appearance of 1,5-naphthalene diamine is gray crystal powder, welcome new and old customers to inquire and discuss business, looking forward to cooperating with you!
