Phenyl-pyrenyl-(3)-diazomethan is a complex organic compound that features a phenyl group (C6H5-), a pyrenyl group (C16H9-), and a diazomethan moiety (CH2N2). This molecule is characterized by its unique structure, where the phenyl and pyrenyl groups are connected to the diazomethan through a carbon-carbon bond. The phenyl group is a benzene ring with a hydrogen atom replaced by a methyl group, while the pyrenyl group is a larger polycyclic aromatic hydrocarbon with a structure similar to that of naphthalene but with an additional benzene ring fused to it. The diazomethan group is known for its ability to transfer a methyl group in various chemical reactions, making Phenyl-pyrenyl-(3)-diazomethan potentially useful in organic synthesis and as a reagent in certain chemical transformations. The specific properties and applications of Phenyl-pyrenyl-(3)-diazomethan would depend on its reactivity, stability, and the context in which it is used.

Check Digit Verification of cas no

The CAS Registry Mumber 855-26-5 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 6 respectively.
Calculate Digit Verification of CAS Registry Number 855-26:
(5*8)+(4*5)+(3*5)+(2*2)+(1*6)=85
85 % 10 = 5
So 855-26-5 is a valid CAS Registry Number.

, p. 679 - 682 (2007/10/02)

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.
