Its strong acidic nature helps to prevent metal corrosion by forming a protective layer on the metal surface, thereby extending the service life of the equipment and reducing maintenance costs.
Used in Cleaning and Detergent Formulations:
3-Sulphophthalic acid is incorporated into cleaning and detergent formulations due to its strong acidic properties and water solubility. It enhances the cleaning efficiency of these products by breaking down and removing stubborn stains, grease, and dirt from various surfaces, making it suitable for use in household and industrial cleaning applications.
Check Digit Verification of cas no
The CAS Registry Mumber 67892-43-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,7,8,9 and 2 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 67892-43:
(7*6)+(6*7)+(5*8)+(4*9)+(3*2)+(2*4)+(1*3)=177
177 % 10 = 7
So 67892-43-7 is a valid CAS Registry Number.

Ti(iv)-based complexes have been demonstrated as candidates for preparing hybrid and functional materials, and have received considerable attention. In this paper, hierarchical hollow titania materials with different surface nanostructures were synthesized successfully using a hydrothermal process via the transformation of a Ti(iv) oxalate complex as a precursor. Different concentrations of ammonia were used to adjust the morphologies and crystalline forms of the hydrothermal products. The hierarchical hollow anatase titania materials, HHTM-1 (cal) and HHTM-2 (cal), have high surface areas of up to 132 m2 g-1 and 84 m2 g-1, respectively, and show superior performance for dye degradation in water.
