Sourcing Beta Naphthol? ChemicalDekho connects you with leading naphthalene derivative manufacturers like Atul Ltd and Sudarshan Chemical. Secure consistent quality for azo dye and pigment synthesis.
Beta Naphthol (CAS 135-19-3) is the backbone of the Azo Dye industry. It is reacted to produce Tobias Acid, J-Acid, and G-Salt, which are precursors for red and orange dyes. It is also used to manufacture rubber antioxidants (PBN) and synthetic tanning agents. Listings specify color stability, as the product tends to darken (turn pink/grey) upon exposure to light/air.
Supply is available in lined bags to prevent oxidation.

Harmful if swallowed or inhaled. Very toxic to aquatic life. Causes skin irritation. Dust may cause eye damage. Light sensitive.
Pure Beta Naphthol is white. However, it oxidizes very easily when exposed to air and light, turning pale pink or grey. This slight discoloration usually does not affect industrial performance.
Tobias Acid (2-Amino-1-naphthalenesulfonic acid) is made from Beta Naphthol. It is the key building block for making Lithol Red (a major plastic pigment).
They are isomers. Alpha Naphthol is used more for insecticides (Carbaryl). Beta Naphthol is used more for dyes and rubber chemicals.
It dissolves in alcohol, ether, and hot water, but crystallizes out when cooled.
