68189-38-8 Usage
Description
2-aminotoluene-3,5-disulphonic acid is an organic compound that consists of aminotoluene with two sulphonic acid groups attached at the 3 and 5 positions on the benzene ring. It is primarily used as an intermediate in the production of various dyes and pigments. The presence of the two sulphonic acid groups makes it water-soluble and allows it to easily react with other compounds in dye synthesis.
Used in Chemical Industry:
2-aminotoluene-3,5-disulphonic acid is used as an intermediate for the production of various dyes and pigments due to its water-solubility and reactivity with other compounds in dye synthesis.
Used in Textile Industry:
2-aminotoluene-3,5-disulphonic acid is used as a precursor for the preparation of metal complex dyes, which are important for the coloring of textiles.
Used in Analytical Chemistry:
2-aminotoluene-3,5-disulphonic acid is used as a pH indicator, taking advantage of its chemical properties to measure the acidity or alkalinity of a solution.
Check Digit Verification of cas no
The CAS Registry Mumber 68189-38-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,8,1,8 and 9 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 68189-38:
(7*6)+(6*8)+(5*1)+(4*8)+(3*9)+(2*3)+(1*8)=168
168 % 10 = 8
So 68189-38-8 is a valid CAS Registry Number.
