It is a yellow crystalline solid that is soluble in water. 4-hydroxy-5-nitro-benzene-1,3-disulfonic acid is characterized by the presence of a hydroxyl group (-OH) at the 4-position, a nitro group (-NO2) at the 5-position, and two sulfonic acid groups (-SO3H) at the 1 and 3 positions of the benzene ring. It is an important intermediate in the synthesis of various dyes and pharmaceuticals, particularly those with azo structures. Due to its reactivity and functional groups, it is used in the production of azo dyes, which are widely used in the textile, paper, and leather industries. The compound's properties, such as its solubility and reactivity, make it a valuable building block in the chemical industry for creating a variety of colorants and other specialty chemicals.
The CAS Registry Mumber 88-28-8 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 8 respectively; the second part has 2 digits, 2 and 8 respectively. Calculate Digit Verification of CAS Registry Number 88-28: (4*8)+(3*8)+(2*2)+(1*8)=68 68 % 10 = 8 So 88-28-8 is a valid CAS Registry Number.
