Acetic anhydride is a colorless liquid with a pungent odor, used as an acetylating agent in organic synthesis. 3-Nitrobenzoic acid is an organic compound with a nitro group attached to the benzene ring, which is used in the synthesis of dyes, pharmaceuticals, and other chemicals. When combined, acetic anhydride and 3-nitrobenzoic acid can form an anhydride, which is a derivative of 3-nitrobenzoic acid. This anhydride is a valuable intermediate in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals, as it can be further reacted to introduce additional functional groups or used in the preparation of esters and amides. The reaction between acetic anhydride and 3-nitrobenzoic acid typically involves the acylation of the carboxylic acid group, leading to the formation of an anhydride bond.

Check Digit Verification of cas no

The CAS Registry Mumber 4015-57-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,0,1 and 5 respectively; the second part has 2 digits, 5 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 4015-57:
(6*4)+(5*0)+(4*1)+(3*5)+(2*5)+(1*7)=60
60 % 10 = 0
So 4015-57-0 is a valid CAS Registry Number.

, p. 4413 - 4416 (2007/10/02)

The palladium(0)-catalyzed reaction of arenediazonium tetrafluoroborates with carbon monoxide and sodium carboxylates in acetonitrile at 25 deg C gave mixed acid anhydrides, ArCOOCOR (Ar = 3-Me-Ph, 4-Me-Ph, 2-MeO-Ph, 4-Br-Ph, 4-I-Ph, 3-NO2-Ph, 4-NO2-Ph, and Ph; R = H, Me, Et, t-Bu, and Ph) in good yields.Homoaromatic acid anhydrides, (ArCO)2O, were obtained by heating of ArCOOCOMe at 100-120 deg C under vacuum.ArCOOCO-t-Bu can be utilized to obtain the corresponding arenecarboxamides by the reaction with some amines.
