Isobutyl-trimethyl plumbane, also known as (isobutyl)trimethylplumbane, is an organolead compound with the chemical formula C7H18Pb. It is a colorless liquid at room temperature and is highly toxic. isobutyl-trimethyl plumbane is formed by the reaction of isobutyl bromide with trimethyl lead in the presence of a base, such as sodium hydride. Isobutyl-trimethyl plumbane is used as an antiknock agent in gasoline, similar to tetraethyl lead, to improve engine performance and reduce engine knocking. However, due to its high toxicity and environmental concerns, its use has been largely phased out in many countries. It is important to handle isobutyl-trimethyl plumbane with extreme care due to its potential health risks and environmental impact.
The CAS Registry Mumber 1907-52-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,0 and 7 respectively; the second part has 2 digits, 5 and 2 respectively. Calculate Digit Verification of CAS Registry Number 1907-52: (6*1)+(5*9)+(4*0)+(3*7)+(2*5)+(1*2)=84 84 % 10 = 4 So 1907-52-4 is a valid CAS Registry Number.
