2-Naphthalenamine(CAS: 91-59-8)

2-Naphthalenamine (CAS: 91-59-8) is a crystalline solid with a molecular weight of approximately 138.15 g/mol. It has a solubility of about 1.8 g/100 mL in water at 20°C. Chemically, it reacts readily with acids to form naphthalen-2-amine hydrochloride. It is slightly soluble in organic solvents like ethanol and acetone. It is used in dye and chemical synthesis due to its reactivity and stability.

2-Naphthalenamine is typically synthesized via reduction of 2-nitronaphthalene using a reducing agent like iron in the presence of concentrated hydrochloric acid. Commonly, a hydrogenation process is employed using a catalyst like Raney nickel. The yield is generally high, and the product is purified through recrystallization.

2-Naphthalenamine (CAS: 91-59-8) is primarily used in the dye industry, where it serves as a precursor for various aromatic dyes. It is also utilized in the synthesis of pharmaceuticals and as a component in some polymer production processes. Additionally, it has applications in the development of sensors and in the production of semiconductors.

When handling 2-Naphthalenamine (CAS: 91-59-8), it is essential to wear appropriate personal protective equipment (PPE) including gloves, safety glasses, and lab coat. Ensure the use of a fume hood during operations. Spills should be cleaned up promptly using suitable absorbent materials. Always refer to the Safety Data Sheet (SDS) for detailed handling and emergency procedures.
