81103-79-9 Usage
General Description
FLUORENE-D10 is a deuterium-labeled derivative of fluorene, a polycyclic aromatic hydrocarbon. It is commonly used as an internal standard in mass spectrometry and analytical chemistry applications to accurately quantify fluorene and other related compounds in samples. FLUORENE-D10 is often preferred over non-labeled fluorene as it allows for precise and accurate measurements due to its deuterium isotopic labeling. This chemical is also used in environmental testing and research to track the presence and fate of fluorene and its derivatives in various matrices such as soil, water, and air. Additionally, FLUORENE-D10 is utilized as a research tool in the study of biotransformation and metabolic processes involving fluorene and other polycyclic aromatic hydrocarbons.
Check Digit Verification of cas no
The CAS Registry Mumber 81103-79-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 8,1,1,0 and 3 respectively; the second part has 2 digits, 7 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 81103-79:
(7*8)+(6*1)+(5*1)+(4*0)+(3*3)+(2*7)+(1*9)=99
99 % 10 = 9
So 81103-79-9 is a valid CAS Registry Number.

Efficient continuous-flow HD exchange reaction of aromatic nuclei in D2O/2-PrOH mixed solvent in a catalyst cartridge packed with platinum on carbon beads

Herein, a continuous-flow deuteration methodology for various aromatic compounds is developed based on heterogeneous platinum-catalyzed hydrogen-deuterium exchange. The reaction entails the transfer of a substrate dissolved in a mixed solvent of 2-propanol and deuterium oxide into a catalyst cartridge packed with platinum on carbon beads (Pt/CB). Pt/ CB could be continuously used without significant deterioration of catalyst activity for at least 24 h. Deuteration proceeded within 60 s of the substrate solutions being passed through the Pt/CB layer in the Pt/CB-packed cartridge.
