organohalogen compound
Vinyl chloride is an organohalogen compound that has important industrial applications. When treated with certain catalysts, vinyl chloride monomers undergo polymerization and form the larger compound known as polyvinyl chloride, or PVC. PVC is used in the manufacture of numerous products, including packaging films and water pipes.
Halothane is a potent organohalogen compound that was introduced into medicine in the 1950s as a general anesthetic. As an inhalation anesthetic, it is administered in vapor form.12
Unlike earlier agents such as ether and chloroform, halothane is nonflammable and nonexplosive, which significantly improved safety during surgical procedures. Additionally, its vapors are neither nauseating nor irritating to a patient's mucous membranes.12
Despite these advantages, halothane is known to depress both respiration and circulation. While it became the most frequently used potent anesthetic shortly after its introduction, its use required careful monitoring due to these physiological effects.1
