The Uses of 3-Chloro-2-methylpropene

3-Chloro-2-methyl-1-propene was used to study ring opening polymerization of oxirane derivatives using organotin phosphate condensate. It was used to study cationic polymerization of 3-Chloro-2-methyl-1-propene using using AICI3 and A3IBr, as initiators.

Definition

ChEBI: 3-Chloro-2-methylpropene is an organochlorine compound.

Biological Functions

MAC is a valuable index for clinical anesthesia, but it is seldom employed without taking other factors into consideration. For example, inhibiting movement in only 50% of patients is not acceptable. Consequently, if an inhalational agent were being used alone—that is, without the administration of other anesthetics or analgesic drugs—the anesthesiologist would employ a multiple of its MAC value to ensure immobility.MAC is frequently multiplied by a factor of 1.3 to achieve nearly 100% clinical efficacy. On the other hand, useful clinical results may be achieved with doses of anesthetics below MAC levels. For example, mild analgesia and amnesia often occur with doses of inhalational agents that are near 0.5 MAC. In this state, it may even be possible to communicate with patients intraoperatively, while their recall is limited.
