α-Diazo-p-nitropropiophenone is a chemical compound with the molecular formula C9H6N4O4. It is a yellow crystalline solid that is sensitive to light and heat, and it decomposes upon exposure to these factors. α-diazo-p-nitropropiophenone is an α-diazo compound, which means it contains a diazo group (-N=N-) bonded to a carbon atom. The p-nitropropiophenone part of the name indicates that the compound has a nitro group (-NO2) attached to a propiophenone moiety, which is a derivative of benzene with a three-carbon chain (propionic acid) attached. α-Diazo-p-nitropropiophenone is used as a reagent in organic synthesis, particularly in the preparation of various heterocyclic compounds and as a precursor for the synthesis of pharmaceuticals and other organic molecules. Due to its reactivity and potential hazards, it is important to handle α-diazo-p-nitropropiophenone with care and in accordance with proper safety protocols.

Check Digit Verification of cas no

The CAS Registry Mumber 20461-79-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,0,4,6 and 1 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 20461-79:
(7*2)+(6*0)+(5*4)+(4*6)+(3*1)+(2*7)+(1*9)=84
84 % 10 = 4
So 20461-79-4 is a valid CAS Registry Number.

The Acid-catalyzed Decomposition of α-Diazo β-Hydroxy Ketones

The proton acid-catalyzed decomposition of 3-aryl-2-diazo-3-hydroxy-1-phenylpropanone (1) gave aryl and hydrogen migration products.The former was the enol-form (2) of 2-aryl-3-phenyl-1,3-propanedione and the latter was the enol- (3) and keto-form (4) of 1-aryl-3-phenyl-1,3-propanedione.The product ratios, 2/(3+4), were affected by the catalysts and solvents used.More polar solvents favored the formation of aryl migration products (2).On the other hand, the BF3-catalyzed decomposition of 1 gave acetylenic ketones as main products along with 2, 3, 4.The TsOH-catalyzed decomposition of 2-diazo-3-hydroxy-3-phenyl-1-indanone, (cyclic α-diazo β-hydroxy ketone), gave 2-phenyl-1,3-indandione quantitatively through phenyl migration.
