Chloralurethane is a compound typically used as a sedative. Its spelling can be confusing due to the presence of several difficult sounds. In IPA phonetic transcription, the word is pronounced as /ˌklɔrəˈljuːrəθeɪn/. The first syllable "chl" is pronounced as "kl," followed by the "o" sound in "lore." The long "u" sound in "lure" comes next, followed by "thane" with the "th" sound as in "thought." Knowing the IPA phonetic transcription helps people to understand the correct spelling of this complex word.
Chloralurethane is a chemical compound and a sedative-hypnotic drug that belongs to the class of drugs known as chloral derivatives. It is also commonly referred to as urethane or ethyl carbamate.
Chloralurethane is primarily used as a sedative and hypnotic agent in the medical field, although it has limited clinical applications compared to other similar drugs. It produces its sedative effects by acting on the central nervous system, depressing neuronal activity and inducing a calming effect on the body.
The compound is typically administered orally or through injection and is rapidly absorbed into the bloodstream. It is then metabolized in the liver and excreted primarily through the kidneys. The sedative effects usually manifest within thirty minutes to an hour, with a duration of action of about six to eight hours. However, individual responses to the drug may vary.
Due to its sedative properties, chloralurethane has historically been used in medical settings to induce general anesthesia. However, its use has declined in recent years due to the development of safer and more effective anesthetic agents.
Like other sedatives, chloralurethane carries the risk of dependence, tolerance, and potential overdose. Prolonged or excessive use of the drug can lead to addiction and withdrawal symptoms upon discontinuation. Therefore, it should be used under careful medical supervision and only for the prescribed purposes.
Ural, made by heating chloral with urethane and treating with hydrochloric and sulphuric acids; occurs in colorless crystals; hypnotic in doses of gr. 10-45 (0.6-3.0).

The word "chloralurethane" is derived from the combination of two chemical compounds: "chloral" and "urethane".
1. "Chloral": The term "chloral" comes from the chemical component "chlor-" referring to chlorine and "-al" indicating the presence of an aldehyde group (-CHO). Chloral is a colorless liquid compound with a pungent odor, also known as trichloroacetaldehyde. It was first synthesized by the German chemist Justus von Liebig in 1832.
2. "Urethane": The term "urethane" originates from "urea", a chemical compound that was discovered in 1773 by the French chemist Hilaire Rouelle. Urea is an organic substance found in urine and other bodily fluids. The suffix "-thane" is borrowed from the alkane hydrocarbon series and indicates a compound having carbon and hydrogen atoms.
