1,4-Dihydroxynaphthalene
CAS Number: 571-60-8
1,4-Dihydroxynaphthalene is a naphthalenediol used as a key intermediate in the synthesis of vat dyes, particularly naphthalene-based quinone vat dyes that exhibit excellent lightfastness and wash fastness on cotton. It is also used in the preparation of anthraquinone derivatives and as a building block for organic semiconductor materials. Chemzip offers this specialty intermediate for high-performance vat dye and organic materials manufacturing.
