SPANIN

SPANIN, also known as 1-naphthylamine, is an organic compound with the chemical formula C10H9N. It is a derivative of naphthalene, consisting of a naphthalene ring system with an amine group attached. SPANIN appears as a colorless solid, though it can darken upon exposure to air and light due to oxidation. It is sparingly soluble in water but readily dissolves in organic solvents such as ethanol and ether.

This compound is primarily used as an intermediate in the synthesis of various dyes and pigments, particularly azo dyes. It also finds application in the production of agricultural chemicals and rubber additives. SPANIN can be synthesized through the reduction of 1-nitronaphthalene.

In terms of safety, SPANIN is considered a hazardous substance. It is toxic if swallowed, inhaled, or absorbed through the skin. Exposure can lead to methemoglobinemia, a condition where the blood's ability to carry oxygen is reduced. It is also a suspected carcinogen. Proper handling procedures, including the use of personal protective equipment and adequate ventilation, are essential when working with SPANIN. Environmental regulations often govern its production, use, and disposal due to its potential toxicity.
