2-Nitro-1-naphthol Chemical Properties,Usage,Production

Description

2-Nitro-1-naphthol is an important organic compound with anti-inflammatory properties used as an analytical method for measuring albumin concentration and as an enzyme-labelled substrate in electrochemical immunoassays. The substance reacts with albumin to form a coloured complex which can be detected spectrophotometrically. It is also used as a model system for the study of inflammatory diseases and inhibits p38 kinase activity. In addition, a derivative of 2-Nitro-1-naphthol (4-nitro-1-naphthol) can be used to prepare chromogenic substrates for neutral or slightly acidic hydrolases.

Chemical Properties

yellow-green to ochre-brown powder and/or chunks

Uses

2-Nitro-1-naphthol was employed as substrate for use in an amperometric 3-electrode system for the determination of alkaline phosphatase, the enzyme label most commonly used in electrochemical immunoassays. It was also used in the preparation of:

di-(2-nitro-1-naphthyl) hydrogen phosphate
1-(2′-methyl-3′-indenyl)-2-naphthylamine and -2-naphthol (axially chiral ligands)

Application

2-Nitro-1-naphthol is commonly used as an intermediate in organic synthesis. It is a derivative of 1-nitro-2-naphthol and 4-nitro-1-naphthol. 1-Nitro-2-naphthol has been found to be a potent inhibitor of enzyme-dependent activation of acetyl-CoA, while 4-nitro-1-naphthol facilitates the preparation of chromogenic substrates for neutral or slightly acidic hydrolases^[1-2].

Purification Methods

Crystallise the naphthol (repeatedly) from EtOH. [Beilstein 6 H 615, 6 III 2938, 6 IV 4236.]
