Description
4-Sulphophthalic anhydride is a reddish-brown syrup that is hygroscopic and fluorescent in solution under UV radiation. It is very soluble in water and alcohol but insoluble in ether and benzene. 4-sulphophthalic anhydride is combustible and is known for its versatile chemical properties.
Uses
Used in Textile Industry:
4-Sulphophthalic anhydride is used as a wetting, cleansing, emulsifying, softening, and equalizing agent for textiles. Its properties allow it to enhance the performance and quality of textile products.
Used in Surface-active Agents:
Derivatives of 4-sulphophthalic anhydride have applications as surface-active agents. These agents are essential in various industries, including detergents, cosmetics, and pharmaceuticals, due to their ability to lower surface tension and improve the interaction between different substances.
Check Digit Verification of cas no
The CAS Registry Mumber 134-08-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 4 respectively; the second part has 2 digits, 0 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 134-08:
(5*1)+(4*3)+(3*4)+(2*0)+(1*8)=37
37 % 10 = 7
So 134-08-7 is a valid CAS Registry Number.
