9,9-dideuteriofluorene is a chemical compound derived from fluorene, a polycyclic aromatic hydrocarbon. It is characterized by the presence of two deuterium atoms (2H) replacing two hydrogen atoms (1H) at the 9th carbon positions in the fluorene molecule. This isotopic substitution can affect the compound's physical and chemical properties, such as its reactivity, stability, and spectroscopic behavior. 9,9-dideuteriofluorene is primarily used in scientific research and chemical analysis, particularly in studies involving isotope labeling and tracing, as well as in the synthesis of other deuterated compounds. Its unique properties make it a valuable tool for understanding the behavior of fluorene and its derivatives in various chemical reactions and processes.

778-60-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 778-60-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 7,7 and 8 respectively; the second part has 2 digits, 6 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 778-60:
(5*7)+(4*7)+(3*8)+(2*6)+(1*0)=99
99 % 10 = 9
So 778-60-9 is a valid CAS Registry Number.

Irradiation of Diazofluorene in Alcohols: Unusual Behaviour of Fluorenyl Ethers

Tomioka, Hideo,Nakamura, Hiroyuki,Izawa, Yasuji

, p. 1070 - 1071 (2007/10/02)

Fluorenyl ethers formed in the reaction of singlet fluorenylidene with alcohols undergo photocleavage to give fluorene and fluorenone, which formally arise from triplet fluorenylidene.
