Phenyl-pyrenyl-(3)-keton-hydrazon is a complex organic compound that features a phenyl group (C6H5-), a pyrenyl group (C16H10-), and a keto-hydrazone functional group. The phenyl group is a benzene ring with a hydrogen atom replaced by a hydrogen atom, while the pyrenyl group is a larger aromatic system consisting of four fused benzene rings. The keto-hydrazone functional group is characterized by a carbonyl group (C=O) bonded to a hydrazone group (-NH-NH2). Phenyl-pyrenyl-(3)-keton-hydrazon is likely to have unique chemical properties due to the combination of these functional groups, and it may be of interest in various fields such as organic chemistry, materials science, and pharmaceutical research.

855-25-4 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 855-25-4 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 8,5 and 5 respectively; the second part has 2 digits, 2 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 855-25:
(5*8)+(4*5)+(3*5)+(2*2)+(1*5)=84
84 % 10 = 4
So 855-25-4 is a valid CAS Registry Number.

1-PYRENYLMETHYL ESTERS, PHOTOLABILE PROTECTING GROUPS FOR CARBOXYLIC ACIDS

Iwamura, Michiko,Ishikawa, Touru,Koyama, Yukiyoshi,Sakuma, Keisuke,Iwamura, Hiizu

, p. 679 - 682 (1987)

1-Diazomethylpyrenes were prepared and reacted with carboxylic acids to give 1-pyrenylmethyl esters.The fluorescent esters were photolysed at 340 nm in methanol to form the starting acids and the corresponding 1-methoxymethylpyrenes in high yields.
