1-[2-(4-chlorobenzoyloxy)-5-methylphenyl]-2-bromoethanone is a complex organic chemical compound with the molecular formula C16H12BrClO3. It is characterized by a 2-bromoethanone group attached to a phenyl ring, which is substituted with a methyl group at the 5-position and a 4-chlorobenzoyloxy group at the 2-position. The 4-chlorobenzoyloxy group itself is a benzoyloxy group with a chlorine atom at the 4-position. 1-[2-(4-chlorobenzoyloxy)-5-methylphenyl]-2-bromoethanone is likely to be used in the synthesis of pharmaceuticals or other organic compounds due to its unique structure and functional groups.

4238-38-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 4238-38-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 4,2,3 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 4238-38:
(6*4)+(5*2)+(4*3)+(3*8)+(2*3)+(1*8)=84
84 % 10 = 4
So 4238-38-4 is a valid CAS Registry Number.

A new synthesis of flavones and pyranoflavone by intramolecular photochemical Wittig reaction in water

Das, Jhantu,Ghosh, Somnath

, p. 7189 - 7194 (2012/01/05)

A new synthetic approach toward the synthesis of flavones and pyranoflavone has been developed by light induced intramolecular photochemical Wittig reaction in water onto aryloxycarbonyl groups and suitably substituted phosphonium bromides sans any phase transfer catalyst or promoter.
