85968-72-5 Usage
General Description
N-Acetoacetyl cresidine is a chemical compound that is used as a diazo coupling component in the production of azo dyes. It is a yellow to dark brown powder with a molecular formula of C11H12N2O2 and a molecular weight of 204.23 g/mol. N-Acetoacetyl cresidine is typically synthesized by condensing acetoacetic acid with 2-amino-4-methylphenol and acetylating the resulting product. It is also used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. However, N-Acetoacetyl cresidine may pose health hazards if inhaled, ingested, or in contact with skin, and proper safety precautions should be taken when handling this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 85968-72-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,5,9,6 and 8 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 85968-72:
(7*8)+(6*5)+(5*9)+(4*6)+(3*8)+(2*7)+(1*2)=195
195 % 10 = 5
So 85968-72-5 is a valid CAS Registry Number.

Knorr cyclizations and distonic superelectrophiles

(Chemical Equation Presented) The acid-catalyzed Knorr cyclization has been studied by experimental and theoretical methods. The results of these studies indicate that β-ketoamides such as acetoacetanilide undergo diprotonation at the two carbonyl oxygen atoms to form distonic superelectrophiles. Direct observation of a dicationic superelectrophile was achieved by low-temperature 1H, 15N, and 13C NMR from FSO 3H-SbF5-SO2ClF solutions. In synthetic studies, the Bronsted superacid CF3SO3H is found to be an effective acid catalyst for the Knorr cyclization.
