Di-(-o-tolyl)-zinndiiodid, also known as bis(2-methylphenyl)zinc iodide, is an organozinc compound with the chemical formula C14H14IZn. It is a white crystalline solid that is sensitive to air and moisture. Di-(-o-tolyl)-zinndiiodid is primarily used as a reagent in organic synthesis, particularly in the formation of carbon-carbon bonds through the Negishi coupling reaction. Di-(-o-tolyl)-zinndiiodid is synthesized by reacting zinc iodide with 2-methylphenylmagnesium bromide. It is an important intermediate in the preparation of various organic compounds, including pharmaceuticals and agrochemicals. Due to its sensitivity, it must be handled under an inert atmosphere, such as nitrogen or argon, to prevent decomposition.
The CAS Registry Mumber 5933-59-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,9,3 and 3 respectively; the second part has 2 digits, 5 and 9 respectively. Calculate Digit Verification of CAS Registry Number 5933-59: (6*5)+(5*9)+(4*3)+(3*3)+(2*5)+(1*9)=115 115 % 10 = 5 So 5933-59-5 is a valid CAS Registry Number.
