The chemical compound "(C4H9)3SnOCH2(C5H8)CH2Br" is a complex organotin compound with a molecular formula that can be broken down into its constituent parts for better understanding. It consists of a tin (Sn) atom at the center, which is bonded to three butyl groups (C4H9), an oxygen atom (O), a methylene group (CH2), a cyclopentyl group (C5H8), and a terminal bromine atom (Br). (C4H9)3SnOCH2(C5H8)CH2Br is likely to be a precursor or intermediate in the synthesis of more complex organotin compounds, which are used in various applications such as catalysts, stabilizers, and biocides. The presence of the bromine atom suggests that it may be involved in reactions where halogen exchange or substitution is a key step. The specific structure and properties of (C4H9)3SnOCH2(C5H8)CH2Br would depend on the stereochemistry and the arrangement of the substituents around the central tin atom.
The CAS Registry Mumber 40894-16-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 4,0,8,9 and 4 respectively; the second part has 2 digits, 1 and 6 respectively. Calculate Digit Verification of CAS Registry Number 40894-16: (7*4)+(6*0)+(5*8)+(4*9)+(3*4)+(2*1)+(1*6)=124 124 % 10 = 4 So 40894-16-4 is a valid CAS Registry Number.
