2-Nitrotoluene-4-sulfonic acid, also known as p-nitrotoluene-4-sulfonic acid, has the chemical formula C7H7NO5S and is a yellow crystalline solid. It is used as an intermediate in the production of dyes, pigments, and pharmaceuticals. The compound is also used as a stabilizer in the production of hydrogen peroxide and as a reagent in organic synthesis. 2-Nitrotoluene-4-sulfonic acid is toxic and can cause irritation to the skin, eyes, and respiratory system. It is important to handle and store this chemical with care and adhere to proper safety protocols to avoid potential health hazards.
Check Digit Verification of cas no
The CAS Registry Mumber 97-06-3 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 9 and 7 respectively; the second part has 2 digits, 0 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 97-06:
(4*9)+(3*7)+(2*0)+(1*6)=63
63 % 10 = 3
So 97-06-3 is a valid CAS Registry Number.

Synthesis of reference substances for highly polar metabolites of nitroaromatic compounds
Schmidt, Torsten C.,Steinbach, Klaus,Buetehorn, Ulf,Heck, Kerstin,Volkwein, Ute,Stork, Gottfried
, p. 3119 - 3130 (2007/10/03)
Transformation processes of nitroaromatic compounds (NAC) lead to polar and highly hydrophilic metabolites. For the unequivocal identification of proposed metabolites reference substances are needed. Since most of them are not commercially available, their synthesis was done in our group. In many cases no satisfying synthesis schemes were found in the literature. In this communication, we therefore describe the preparation, structural elucidation and separation of 17 compounds. Many of the newly synthesized analytes were found in various water samples from a former ammunition plant.
