64609-91-2 Usage
General Description
Pentafluoropropionyl bromide, also known as PFPB, is a colorless, highly reactive liquid compound with the chemical formula C3F5COBr. It is a powerful acylating reagent and is commonly used as a building block in the synthesis of various organic compounds. PFPB reacts violently with water, alcohols, and amines, producing toxic fumes, so it is handled with extreme caution. It is also used as a reagent in the preparation of pharmaceuticals, agrochemicals, and other specialty chemicals. Pentafluoropropionyl bromide is a highly specialized chemical that is often used in research and industrial applications requiring precise control of acylation reactions.
Check Digit Verification of cas no
The CAS Registry Mumber 64609-91-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,4,6,0 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 64609-91:
(7*6)+(6*4)+(5*6)+(4*0)+(3*9)+(2*9)+(1*1)=142
142 % 10 = 2
So 64609-91-2 is a valid CAS Registry Number.

Facile conversion of perfluoroacyl fluorides into other acyl halides
Fukaya, Haruhiko,Matsumoto, Tomonori,Hayashi, Eiji,Hayakawa, Yoshio,Abe, Takashi
, p. 915 - 920 (2007/10/03)
Nine perfluoroacyl fluorides underwent halogen exchange when treated with anhydrous lithium halides to give acyl chlorides, bromides and iodides in high yields. The temperature dependence of this reaction is described. In the reaction with perfluorodiacyl fluoride, the diacyl halides possessing different acyl halide-groups were also produced. Of the alkaline metal salts used halogen exchange was successful only with lithium salts because of the interaction between lithium and fluorine.
