1,4-Naphthoquinone

1,4-Naphthoquinone (CAS 130-15-4, EC 204-977-6, formula C10H6O2) is an aromatic diketone derived from naphthalene, commercially available under trade names including Quino Power NQ and Quino Power NQI, and referenced in research literature as NSC 9583 and NSC 113960. No E-code designation applies to this substance.

In textile and leather dyeing, 1,4-Naphthoquinone functions as an oxidative catalyst and colorant precursor, accelerating dye fixation reactions through its reactive quinone carbonyl groups. In personal care formulations, it serves as a hair dye intermediate and skin conditioning agent, where its redox activity enables controlled color development at the fiber or skin surface. It is also used as a catalyst in printing ink systems within the packaging sector.

This material is supplied as a crystalline powder compliant with REACH registration requirements for the European market. Standard packaging formats include fiber drums and multi-layer bags suited to industrial procurement volumes. Buyers should confirm purity grade specifications and SDS documentation prior to ordering.
