Dichlorofluoromethanesulphenyl bromide, also known as 2,2-dichloro-1,1,1-trifluoroethylsulfonyl bromide or DCFMSB, is a chemical compound with the molecular formula C2BrCl2F3O2S. It is a colorless, oily liquid that is highly reactive and sensitive to moisture. DCFMSB is primarily used as a reagent in organic synthesis, particularly for the preparation of sulfonamides and sulfonate esters. It is also employed in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals. Due to its reactivity, DCFMSB requires careful handling and storage to prevent unwanted side reactions and degradation.
The CAS Registry Mumber 993-36-2 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 9,9 and 3 respectively; the second part has 2 digits, 3 and 6 respectively. Calculate Digit Verification of CAS Registry Number 993-36: (5*9)+(4*9)+(3*3)+(2*3)+(1*6)=102 102 % 10 = 2 So 993-36-2 is a valid CAS Registry Number.
