(C4H9)tri-2,5-xylylstannane, also known as tris(2,5-dimethylphenyl)stannane, is an organotin compound with the chemical formula C24H31Sn. It is a colorless, crystalline solid that is soluble in organic solvents. (C4H9)tri-2,5-xylylstannane is composed of a central tin atom bonded to three 2,5-dimethylphenyl ligands, which are aromatic rings with two methyl groups attached at the 2 and 5 positions. Organotin compounds like this are of interest due to their potential applications in various fields, including as catalysts, stabilizers, and in the synthesis of other organometallic compounds. They are also known for their biocidal properties, which have led to their use in antifouling paints and as pesticides, although environmental concerns have limited their application in recent years. The compound's stability, reactivity, and specific uses are influenced by the steric bulk and electronic properties of the 2,5-dimethylphenyl groups.
The CAS Registry Mumber 74475-79-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,4,4,7 and 5 respectively; the second part has 2 digits, 7 and 9 respectively. Calculate Digit Verification of CAS Registry Number 74475-79: (7*7)+(6*4)+(5*4)+(4*7)+(3*5)+(2*7)+(1*9)=159 159 % 10 = 9 So 74475-79-9 is a valid CAS Registry Number.
