9,1,1-Trichloroethane 

Sarcastic term used for any toxic compound, often spoken in an anxious/alarmed tone of voice to indicate the speaker's horror or distress at even the thought/possibility of said chemical being used, and implying to any listeners that he fears that the use of said chemical might very likely necessitate calling 911.

Homeowner: Now, wait a sec --- I got toddlers and pets, remember! You’re not gonna use some kinda dangerous 9,1,1-Trichloroethane-crap on my floor, are you?
Carpet-cleaning service guy: Oh, no, Ma'am --- this is all environmentally-friendly detergent --- 100% natural and biodegradable ingredients.

dichloro-diphenyl-trichlorothane 

Most commonly known as DDT, this is a chemical that was widely used as a pesticide (particularly for mosquito control) in the 1990's before being banned across the board by all states.

If I were to kill a midget, perhaps the best methos would be to lace his drink with a little dichloro-diphenyl-trichlorothane.

Trichloroethylene 

Basically the pseudo-chloroform. It weighs almost same as chloroform, smells almost exactly like chloroform (but milder) and looks exactly chloroform. Like chloroform, trichloroethylene was also used as an anaesthetic. It is believed to be "less toxic" than chloroform while being a certified carcinogen and degreasing nerves in the face. Trichloroethylene is a professional water and soil pollutant, despite being volatile.

Trichloroethylene is main antagonist in the movie A Civil Action, it gave kids cancer via the tap water.
