78112-48-8 Usage
General Description
1,4-bis(4-methylphenyl)-2,3-diphenyl-9H-fluorene is a complex chemical compound belonging to the fluorene family. It is made up of two 4-methylphenyl groups and two phenyl groups attached to the fluorene backbone. 1,4-bis(4-methylphenyl)-2,3-diphenyl-9H-fluorene is commonly used in materials chemistry and organic electronic devices due to its high thermal stability, good charge-transport properties, and high quantum yield. It can also be used as a fluorescent probe for detecting certain biological molecules and as a precursor for the synthesis of various functional materials. However, due to its complex structure and potential reactivity, proper handling and precautions are necessary when working with this chemical.
Check Digit Verification of cas no
The CAS Registry Mumber 78112-48-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,8,1,1 and 2 respectively; the second part has 2 digits, 4 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 78112-48:
(7*7)+(6*8)+(5*1)+(4*1)+(3*2)+(2*4)+(1*8)=128
128 % 10 = 8
So 78112-48-8 is a valid CAS Registry Number.

, p. 91 - 94 (2007/10/02)
1,3-Diaryl-2,8-dihydro-2,8-dioxocyclopentadienes (IV) have been prepared from ninhydrin hydrate (I) and 4,4'-disubstituted dibenzyl ketones (II).During the formation of (IV), a side product has also been isolated, and assigned structure (V) based on chemical and spectral evidences.The dienones (IV) readily undergo cycloaddition reaction with ethylenic and acetylenic compounds forming fluorenone derivatives which on subsequent reduction afford fluorenones.
