Uses
Used in Textile Industry:
AHNS is used as a fluorescent whitening agent for textiles to improve the appearance of fabrics by making them appear brighter and more vivid. The optical brightening effect is particularly useful in enhancing the visual appeal of colored and white textiles.
Used in Paper Industry:
In the paper industry, AHNS is utilized as an optical brightener to increase the whiteness and brightness of paper products. This is crucial for improving the readability and aesthetic quality of printed materials.
Used in Plastics Industry:
AHNS is employed as a brightening agent in the plastics industry to enhance the visual appeal of plastic products. Its ability to improve the color and brightness of plastics makes it a valuable additive in the production of items ranging from packaging materials to consumer goods.
Used in Detergent Industry:
AHNS is used in detergents and laundry products as a whitening agent to make fabrics appear cleaner and brighter. 7-(acetylamino)-4-hydroxy-2-Naphthalenesulfonicacid's fluorescent properties help to mask the appearance of stains and dirt, giving clothes a fresher and more vibrant look.
Used in Pharmaceutical Industry:
AHNS is used as a fluorescent dye in the pharmaceutical industry, particularly for cell imaging and cancer research. Its fluorescent properties allow researchers to visualize cellular structures and processes, aiding in the study of various diseases and the development of new treatments.
Used in Research and Development:
AHNS is also used in research and development settings for the creation of new materials and technologies that leverage its fluorescent and brightening properties. This includes applications in the development of sensors, imaging technologies, and other advanced materials with specific optical properties.
Check Digit Verification of cas no
The CAS Registry Mumber 6334-97-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 6,3,3 and 4 respectively; the second part has 2 digits, 9 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 6334-97:
(6*6)+(5*3)+(4*3)+(3*4)+(2*9)+(1*7)=100
100 % 10 = 0
So 6334-97-0 is a valid CAS Registry Number.

, (2008/06/13)
The invention relates to novel useful reactive dyes of the formula I STR1 in which: F is a radical selected from the group consisting of metal-free or metal-containing monoazo or disazo dyes containing at least one --SO3 H group, anthraquinone dyes, sulfophthalocyanine dyes, formazan dyes, phenazine dyes, oxanine dyes and nitroaryl dyes, R is hydrogen, C1 -C4 alkyl which is unsubstituted or substituted with --COOH or --SO3 H, cyanoethyl, or hydroxyethyl, X is fluorine, chlorine, bromine, --SO3 H, phenylsulfonyl or C1 -C4 -alkylsulfonyl, P is 1 or 2 and A is a radical of the formula STR2 in which: the groups designated "alk" are independently of each other straight or branched polymethylene radicals having 2 to 6 carbon atoms, and Z is β-halogenoethyl, vinyl, β-sulfatoethyl, β-thiosulfatoethyl or βacetoxyethyl.
Selective acylation of hydroxy-amino-arylsulfonic acids
-
, (2008/06/13)
An improved process for selectively N-acylating hydroxy-amino-arylsulfonic acids is disclosed wherein the hydroxy-amino-arylsulfonic acid is dissolved in water by treatment with an alkaline lithium salt, such as lithium hydroxide, and the acylation is conducted while maintaining the pH at about 3-6. The N-acyl-hydroxy-amino-arylsulfonic acids are useful as dyestuff precursors.
