CAS 118-46-7

1-amino-7-naphthol

Description:

1-Amino-7-naphthol, with the CAS number 118-46-7, is an organic compound characterized by the presence of an amino group (-NH2) and a hydroxyl group (-OH) attached to a naphthalene ring system. This compound appears as a solid, typically exhibiting a dark color due to the naphthalene structure, which is known for its aromatic properties. It is soluble in organic solvents and has limited solubility in water, reflecting its hydrophobic naphthalene core. 1-Amino-7-naphthol is primarily used in the dye industry, particularly in the synthesis of azo dyes, due to its ability to form stable colored complexes. Additionally, it has applications in analytical chemistry as a reagent for detecting certain metal ions. The compound is sensitive to light and can undergo oxidation, which may affect its stability and reactivity. Safety precautions should be taken when handling this substance, as it may pose health risks if ingested or inhaled, and appropriate protective measures should be employed to minimize exposure.

8-Amino-2-naphthol (8AN) is a natural product that has been found to have anti-inflammatory, antioxidant, and antiviral properties in vitro. It has been shown to inhibit the production of protonated species of 8AN by adding a proton to the hydroxyl group on the naphthalene ring. This reaction occurs at an activation energy of 17.2 kJ/mol and is reversible, with a protonation equilibrium constant of 1.0 x 10 M. The intramolecular hydrogen transfer mechanism is shown in Figure 1 below:
