Tri-β-phenethyltin bromide, also known as triphenyltin bromide or (C6H5CH2SnBr3)3, is an organotin compound characterized by its three β-phenethyl groups attached to a central tin atom. tri-β-phenethyltin bromide is a white crystalline solid with a melting point of 154-156°C and is soluble in organic solvents such as ethanol, acetone, and dichloromethane. It is primarily used as a fungicide in agriculture, particularly for the control of various plant diseases caused by fungi, algae, and bacteria. Due to its broad-spectrum activity and effectiveness, tri-β-phenethyltin bromide has been widely applied in the protection of crops like rice, wheat, and vegetables. However, concerns about its environmental impact and potential toxicity to non-target organisms have led to a decrease in its usage in recent years.
The CAS Registry Mumber 97664-46-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,7,6,6 and 4 respectively; the second part has 2 digits, 4 and 6 respectively. Calculate Digit Verification of CAS Registry Number 97664-46: (7*9)+(6*7)+(5*6)+(4*6)+(3*4)+(2*4)+(1*6)=185 185 % 10 = 5 So 97664-46-5 is a valid CAS Registry Number.
