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. | [Synthesis Reference(s)]

3-Chloro-2-methylpropene is reasonably anticipated to be a human carcinogen based on sufficient evidence of carcinogenicity from studies in experimental animals. | [Toxics Screening Level]
The initial risk screening level (IRSL) is 0.03μg/m3 with an annual averaging time. |
| Questions And Answer | Back Directory | [Description]
3-Chloro-2-methylpropene is used as an intermediate to produce carbofuran, herbicides, plastics, pharmaceuticals and other organics. It is also used as an additive in textile and perfumes. It was used to study ring opening polymerization of oxirane derivatives using organotin phosphate condensate and cationic polymerization of 3-Chloro-2-methylpropene with AICI3 and AIBr3 as initiators. It is also the reactant for the synthesis of cyclobutanone.
