General Description

4-(Difluoromethoxy)phenacyl bromide is a chemical compound with the formula C9H8BrF2O2. It is often used as a reagent in organic synthesis and as a protecting group for alcohols and phenols. This chemical is a strong electrophile and reacts readily with nucleophiles, making it useful for the formation of carbon-carbon and carbon-oxygen bonds in various organic reactions. It is also known for its potential applications in pharmaceutical and agrochemical research as a building block for the synthesis of biologically active compounds. Additionally, 4-(Difluoromethoxy)phenacyl bromide is known to have moderate acute toxicity and should be handled with care in a laboratory setting.

Check Digit Verification of cas no

The CAS Registry Mumber 141134-24-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,4,1,1,3 and 4 respectively; the second part has 2 digits, 2 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 141134-24:
(8*1)+(7*4)+(6*1)+(5*1)+(4*3)+(3*4)+(2*2)+(1*4)=79
79 % 10 = 9
So 141134-24-9 is a valid CAS Registry Number.

Preparation and use of α-bromomono- and -bromobis-difluoromethoxyacetophenones in the synthesis of polymethyleneimidazoles with an angular nitrogen atom

Demchenko,Nazarenko,Fedyuk,Fialkov,Shelyazhenko,Yagupol'skii

, p. 1191 - 1195 (2007/10/03)

The synthesis of α-bromo-4-difluoromethoxy- and α-bromo-2,4-bis(difluoromethoxy)acetophenones has been earned out. Conditions have been studied for condensing the latter with cyclic tri- and tetramethylenamidinines and with pyridine-containing derivatives. A series of pyrrolo[1,2-a]imidazole and imidazo[2,1-a]pyridine derivatives containing difluoromethoxy groups has been synthesized. 1998 Plenum Publishing Corporation.
