5(4H)-Thebenidinone, also known as 5(4H)-oxazolone, is a heterocyclic organic compound with the molecular formula C8H7NO2. It is a white crystalline solid that is derived from thebaine, an alkaloid found in opium poppy. 5(4H)-Thebenidinone is of interest in the field of organic chemistry and has been studied for its potential applications in the synthesis of various pharmaceuticals and other chemical compounds. 5(4H)-Thebenidinone is characterized by its unique oxazolone ring structure, which contributes to its chemical properties and reactivity. It is typically synthesized through a series of chemical reactions involving thebaine, and its derivatives have been explored for their potential therapeutic effects, although further research is needed to fully understand its applications and safety profile.

64884-40-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 64884-40-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,8,8 and 4 respectively; the second part has 2 digits, 4 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 64884-40:
(7*6)+(6*4)+(5*8)+(4*8)+(3*4)+(2*4)+(1*0)=158
158 % 10 = 8
So 64884-40-8 is a valid CAS Registry Number.

Schmidt reaction of some constrained aromatic acids, and related topics

Ruediger, Edward H.,Gandhi, Sham S.,Gibson, Martin S.,Farcasiu, Dan,Uncuta, Cornelia

, p. 577 - 579 (2007/10/02)

Schmidt reaction of phthalic acid in 90-98percent sulfuric acid gives anthranilic acid and anthranilazide (major products) by a process considered to involve 3,1-benzoxazin-2,4(1H)-dione as intermediate.Benzimidazol-2-one is produced in this reaction by a secondary process from anthranilazide; it is also produced by photolysis of anthranilazide.Under Schmidt reaction conditions, 1,2,3-benzotriazin-4(3H)-one gives o-azidobenzamide.Under similar conditions, the lactol of 4-formyl-5-phenanthroic acid gives 1-azapyren-2(1H)-one and phenanthrene-4,5-dicarboximide, while phenanthrene-4,5-dicarboxylic acid gives 1-azapyren-2(1H)-one.Diphenic acid yields phenanthridone and 2,2'-diaminobiphenyl in proportions dependent on the sulfuric acid concentration.
