71735-32-5 Usage
Uses
PFPI may be used to incubate the lyophilized samples, for derivatization during GC/MS analysis to measure total d-chiro-Inositol content absorbed by rodents.
General Description
Derivatization before a GC analysis helps in yielding distinctive products, which can be achieved using a derivatizing reagent that reacts with amino and hydroxyl functionalities quantitatively. 1-(Pentafluoropropionyl)imidazole (PFPI) is a derivatizing reagent which was found to give high yield of products than pentafluoropropionic anhydride during preparation of methyl ester/pentafluoropropionyl derivatives.
Check Digit Verification of cas no
The CAS Registry Mumber 71735-32-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,1,7,3 and 5 respectively; the second part has 2 digits, 3 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 71735-32:
(7*7)+(6*1)+(5*7)+(4*3)+(3*5)+(2*3)+(1*2)=125
125 % 10 = 5
So 71735-32-5 is a valid CAS Registry Number.

Khlebnicova,Isakova,Baranovsky,Borisov,Lakhvich
, p. 1564 - 1569 (2008/09/18)
A one-pot synthesis of 2-perfluoroalkanoylcyclohexane-1,3-diones via C-acylation of cyclohexane-1,3-diones with N-perfluoroacylimidazole as an acylating agent is reported. A reaction was examined with isolated N-trifluoroacetylimidazole and with N-perfluoroacylimidazoles generated in situ from perfluorocarboxylic acid anhydrides or perfluorocarboxylic acids.
