Toxaphene

Toxaphene (also known as chlorinated camphene) is a mixture of approximately 200 organic compounds, formed by the chlorination of camphene (C10H16) to an overall chlorine content of 67-69 % by weight. The bulk of the compounds (mostly chlorobornanes, chlorocamphenes, and other bicyclic chloroorganic compounds) found in Toxaphene have chemical formulas ranging from C10H11Cl5 to C10H6Cl12, with a mean formula of C10H10Cl8. The formula weights of these compounds range from 308 to 551 grams/mole; the theoretical mean formula has a value of 414 grams/mole. Toxaphene is usually seen as a yellow to amber waxy solid but may occur as a gas. It has a piney odour and is volatile enough to be transported for long distances through the atmosphere. [1,2]
