2,3,4,5,6-Pentafluorophenyl difluoromethyl 4-bromophenyl carbonate, also known as "2.3.4.5.6-Pentafluor-phenylessigsaeure-(4-brom-phenacylester)", is a complex organic compound with the chemical formula C13H3BrF6O3. 2.3.4.5.6-Pentafluor-phenylessigsaeure-(4-brom-phenacylester) is characterized by a pentafluorophenyl group (C6HF5) attached to a difluoromethyl carbonate moiety, which is further esterified with a 4-bromophenyl group (C6H4Br). It is a colorless to pale yellow liquid and is used as a reagent in organic synthesis, particularly in the preparation of various pharmaceuticals and agrochemicals. Due to its reactivity and the presence of multiple functional groups, it is handled with care in a controlled laboratory environment.
The CAS Registry Mumber 2260-89-1 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,2,6 and 0 respectively; the second part has 2 digits, 8 and 9 respectively. Calculate Digit Verification of CAS Registry Number 2260-89: (6*2)+(5*2)+(4*6)+(3*0)+(2*8)+(1*9)=71 71 % 10 = 1 So 2260-89-1 is a valid CAS Registry Number.
