4-Amino-2-methyl-1-naphthol

4-Amino-2-methyl-1-naphthol is an organic compound with the molecular formula C11H11NO. It is a derivative of naphthol, a type of phenol derivative that is often used in the manufacturing of dyes and pigments. The compound is characterized by the presence of an amino group (-NH2) and a methyl group (-CH3) attached to a naphthol base.

Structure and Properties

The structure of 4-Amino-2-methyl-1-naphthol consists of a naphthol base, which is a fused two-ring system (naphthalene) with a hydroxyl group (-OH) attached. The 4-amino group is attached to the fourth carbon of the naphthalene ring, and the 2-methyl group is attached to the second carbon.

This compound exhibits typical properties of both phenols and amines. Like other phenols, it can form hydrogen bonds due to the presence of the hydroxyl group. The amino group makes it a weak base, capable of accepting a proton.

Synthesis

The synthesis of 4-Amino-2-methyl-1-naphthol can be achieved through a multi-step process. The process typically begins with the nitration of 2-methyl-1-naphthol, followed by a reduction step to introduce the amino group.

Applications
