purposes: chemical properties; colorless or yellow rhombus crystal or powder. Has an unpleasant phenol odor. Soluble in alcohol, ether, benzene, chloroform and alkali solution, insoluble in water. Uses; used as analytical reagents, and also used in organic synthesis; synthetic rubber antioxidants, pesticides, fragrances, dyes, etc.; 1-naphthol, also known as α-naphthol, cresol, α-hydroxynaphthalene, is a A key intermediate in the production of the insecticide carbaryl. 1-Naphthol is used in the dye industry to produce acid yellow 1, acid orange 20, mordant black 3, mordant black 11, solvent red 3, solvent orange 5, oil palm GB, etc. It can be used in the pharmaceutical industry to manufacture preservatives and Anti-corrosion drugs, etc., are also effective antioxidants for many aldehydes, mineral oils and vegetable oils, and are widely used in synthetic fragrances, rubber anti-aging agents and color formers for film films. Uses; the demand for 1-naphthol is roughly only about 5% of that of 2-naphthol. However, 1-naphthol is in great demand as a raw material for the pesticide carbaryl. Intermediates derived from 1-naphthol are N-phenyl-1-naphthylamine, N-ethyl-1-naphthylamine, N-cyclohexyl-1-naphthylamine, 1-hydroxy-2-naphthoic acid , 1-naphthol-2-sulfonic acid, 1-naphthol-4-sulfonic acid, 1,7-Kleigh acid, acetamido-7-naphthol, 2,4-dinitronaphthol, etc.

Used in the dye industry to produce Acid Yellow 1, Acid Orange 20, Mordant Black 3, Mordant Black 11, Solvent Red 3, Solvent Orange 5, Oil Palm GB, etc. In the pharmaceutical industry, it can be used to manufacture preservatives and anti-mild rheumatism drugs. It is also an effective antioxidant for many aldehydes, mineral oils and vegetable oils, and is widely used in synthetic fragrances, rubber antioxidants and color formers for film films. Uses; colorimetric determination of titanium, niobium, tungsten, germanium, vanadium, nitrite and copper; determination of tyrosine and protein; used as basic raw materials or intermediates for dyes, pesticides, spices and rubber antioxidants and color films film coupler
