Pronunciation: [kɹˈɛsɒl] (IPA) 
Kresol is a chemical compound with the molecular formula C7H8O. It is also known as hydroxytoluene, and it has a distinctive aroma. The word kresol is spelled with a "k" instead of the more common "c" due to its German origin, where the letter "k" is often used in place of the letter "c." The word is pronounced as /ˈkrɛsɒl/ according to the International Phonetic Alphabet, with the stress on the first syllable.
Kresol is a noun that refers to any of three isomeric forms of a synthetic, colorless, crystalline compound known as cresol. The three isomers are ortho-cresol, meta-cresol, and para-cresol, which differ in the positioning of the functional groups on the benzene ring. Kresol is typically derived from coal and tar or produced synthetically, and it is commonly used as an intermediate in the synthesis of various chemicals.
Kresol has a distinct phenolic odor and is mildly soluble in water, but highly miscible in organic solvents such as alcohols, ether, and benzene. It is a powerful disinfectant and antiseptic agent due to its antimicrobial properties. In industries, kresol is utilized as a solvent, preservative, and as an ingredient in the production of resins, dyes, and plastics.
Due to its toxicity, prolonged exposure or ingestion of kresol may cause harmful effects on human health, including skin and eye irritation, respiratory issues, and gastrointestinal problems. Hence, appropriate safety precautions and protective measures are necessary when handling kresol.
In summary, kresol is a term used to describe any of the three isomers of cresol, which are synthetic compounds primarily employed as intermediates in chemical processes. It possesses disinfectant properties and finds application in a range of industrial processes, though caution must be exercised to avoid adverse health effects.

The word "kresol" has its etymological roots in the German language. It is derived from the German word "Kresol", which was coined by chemist Auguste Laurent in 1838. Laurent named the compound after "Kreosote", an oily substance derived from wood tar that has similar chemical properties. The word "Kreosote" itself comes from the Greek word "kreas" meaning "flesh" and "sōtēr" meaning "preserver" or "savior", as it was used as a preservative for meat.
