2246-48-2 Usage
General Description
2-Acetyl-3-hydroxy-1,4-naphthalenedione, also known as juglone, is a natural organic compound found in the leaves, roots, and bark of walnut trees, as well as in other plant species. It is a phenolic compound with a yellow hue and is often used for its antimicrobial, antifungal, and allelopathic properties. Juglone is known to inhibit the growth of competing plant species, which has led to its use as a natural herbicide in agricultural and horticultural practices. In addition, it has also been used in the production of dyes and pigments due to its ability to bond with proteins and other organic compounds, creating a durable color. However, juglone can be toxic to certain plants, animals, and microorganisms, and caution should be exercised when using or handling this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 2246-48-2 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,4 and 6 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 2246-48:
(6*2)+(5*2)+(4*4)+(3*6)+(2*4)+(1*8)=72
72 % 10 = 2
So 2246-48-2 is a valid CAS Registry Number.

Method for dyeing keratinous fibres using a monohydroxyindole or dihydroxyindole and a non-oxidizing aromatic carbonyl derivative and dyeing agent
-
, (2008/06/13)
The present invention relates to a method for dyeing keratinous fibers, characterized in that the following are applied to the fibers: a) a composition (A) containing, in a medium appropriate for dyeing, at least one monohydroxyindole or dihydroxyindole, this application being preceded or followed by the application of b) a composition (B) containing, in a medium appropriate for dyeing, at least one aromatic carbonyl derivative chosen from hydroxyacetophenones, hydroxybenzophenones, 2-hydroxy-1,4-benzoquinones, hydroxy-1,4-naphthoquinones,amino-1,4-naphthoquinones,hydroxy-9,10-anthraquinones and amino-9,10-anthraquinones. It also relates to the dyeing agents for carrying it out.
