Dibenzobromolium, also known as 1,2-dibromodibenzo[b,f]oxaphosphorin-6-ium, is a chemical compound with the molecular formula C12H8Br2O2P. It is a derivative of dibenzooxaphosphorin, a heterocyclic compound containing phosphorus, oxygen, and carbon atoms. Dibenzobromolium is characterized by the presence of two bromine atoms attached to the dibenzooxaphosphorin core, which imparts unique chemical properties to the molecule. Dibenzobromolium is primarily used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the generation of carbocations. Its stability and reactivity make it a valuable tool in the synthesis of various organic compounds, including pharmaceuticals and agrochemicals.
The CAS Registry Mumber 244-34-8 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 2,4 and 4 respectively; the second part has 2 digits, 3 and 4 respectively. Calculate Digit Verification of CAS Registry Number 244-34: (5*2)+(4*4)+(3*4)+(2*3)+(1*4)=48 48 % 10 = 8 So 244-34-8 is a valid CAS Registry Number.
