naphthalene-1,2-diamine - Introduction
naphthalene-1,2-diamine(naphthalene-1) is an organic compound with the chemical formula C10H9N2. It is a derivative of naphthalene with two amino groups located on carbons 1 and 2 of the naphthalene molecule.
naphthalene-1,2-diamine is a solid and can form yellow to brown crystals. It has a strong odor and has good solubility. It is alkaline in solution.
naphthalene-1, the main use of 2-diamine is as an intermediate in organic synthesis. It can be used to synthesize dyes, pigments and photosensitive materials. It can also be used in the preparation of organic synthesis catalysts and pharmaceuticals.
The method of preparing naphthalene-1,2-diamine can be achieved by the reduction of nitronaphthalene. Nitrosamines and ferrous or tadine salts are typically used to reduce the nitronaphthalene to give 1,2-diaminonaphthalene.
Regarding safety, naphthalene-1,2-diamine needs to be handled carefully. It may irritate the eyes, skin and respiratory system. Appropriate personal protective measures, such as gloves, goggles and protective masks, are required during use or storage. In addition, they should be kept away from open flames and protected from light. If swallowed or inhaled, seek medical attention immediately. When using or handling naphthalene-1,2-diamine should follow the relevant safety procedures.
