General Description
N-Acetyl-4-nitro-1-naphthylamine is a chemical compound that is commonly used in the production of dyes and optical brighteners. It is a yellow to brownish crystalline solid with a melting point of 153-154°C. N-ACETYL-4-NITRO-1-NAPHTHYLAMINE is known to be carcinogenic and has been linked to bladder cancer in humans. It is important to handle this chemical with care and to use appropriate safety measures when working with it. N-Acetyl-4-nitro-1-naphthylamine should be stored in a cool, dry place and kept away from incompatible materials. Additionally, it is essential to avoid ingestion, inhalation, and skin or eye contact with this compound due to its toxic and harmful nature.
Check Digit Verification of cas no
The CAS Registry Mumber 24402-72-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,4,4,0 and 2 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 24402-72:
(7*2)+(6*4)+(5*4)+(4*0)+(3*2)+(2*7)+(1*2)=80
80 % 10 = 0
So 24402-72-0 is a valid CAS Registry Number.

An efficient and one-pot synthetic method for the regioselective ortho-nitration of the N-phenyl carboxamides and primary anilines has been developed by using bismuth nitrate and acetic anhydride as the nitrating reagents. Reaction proceeds at room temperature and results in corresponding ortho-nitrated products in moderate to excellent yields. This method provides an operationally simple, regioselective, and efficient access to synthesize o-nitro anilines under the mild conditions.
