1325-35-5 Usage
Uses
Used in Textile Industry:
Benzenesulfonic acid, 2-methyl-5-nitro-, alk. cond. products, reduced is used as a dyeing agent for cellulose fibers, silk, and wool fabrics. It is particularly useful for dyeing and printing on these materials due to its color-changing properties and solubility in water and soluble fiber elements.
Used in Leather and Paper Shading:
The compound is also used for shading in the leather and paper industries, where its color-changing properties and solubility in water make it an effective agent for adding color and depth to these materials.
Standard:
The compound meets certain industry standards for acid resistance, alkali resistance, light fastness, soaping, water fading, and stain fading. These properties make it a reliable and durable choice for various applications in the textile, leather, and paper industries.

Check Digit Verification of cas no
The CAS Registry Mumber 1325-35-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 5 respectively; the second part has 2 digits, 3 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 1325-35:
(6*1)+(5*3)+(4*2)+(3*5)+(2*3)+(1*5)=55
55 % 10 = 5
So 1325-35-5 is a valid CAS Registry Number.
