Cresylic acid is a term used to describe a mixture of isomeric phenols having a formula of C8H10O. The spelling of this word is determined by utilizing the International Phonetic Alphabet (IPA) which is a system of phonetic notation based primarily on the Latin alphabet. The IPA spelling of "cresylic acid" is /krɛˈsɪlɪk/ ˈæsɪd/. This chemical substance is utilized as a solvent for the production of herbicides, insecticides, and in pharmaceutical applications. The spelling of cresylic acid is crucial for understanding its properties and uses.
Cresylic acid, also known as cresols, refers to a group of organic compounds that belong to the class of phenols. These compounds are derived from coal tar or petroleum and are typically composed of three isomers, namely ortho-cresol, meta-cresol, and para-cresol. Each isomer has a distinct chemical structure, resulting in different physical and chemical properties.
Cresylic acid is characterized by its oily, colorless to yellowish appearance, and it possesses a characteristic phenolic odor. It is slightly soluble in water but exhibits higher solubility in organic solvents such as ethanol, benzene, and ether.
These compounds find various applications in different industries. One common application is in the manufacturing of disinfectants, as cresylic acid exhibits antimicrobial properties. It is also utilized in the production of resins, dyes, and perfumes. Moreover, this compound is employed as a precursor in the synthesis of other chemicals like pesticides and pharmaceuticals.
Cresylic acid can be toxic if ingested, inhaled, or absorbed through the skin. It may cause irritation and corrosion, leading to severe burning or tissue damage. Furthermore, prolonged exposure to cresylic acid can have detrimental effects on human health, including respiratory and digestive problems, as well as potential liver and kidney damage.
In summary, cresylic acid refers to a group of organic compounds derived from coal tar or petroleum, consisting of three isomers. These compounds serve various industrial purposes but must be handled with caution due to their toxic nature.

The word "cresylic acid" derives its etymology from the prefix "cresyl" and the suffix "ic acid".
The term "cresyl" comes from "cresol", which refers to a class of aromatic organic compounds. The word "cresol" is derived from "cresos" in Greek, meaning "flesh", due to the odor these compounds possess. "Cresol" is also related to "crescere", a Latin word that means "to grow" or "to increase", as cresols were initially obtained from the distillation of crude coal tar, which expands during the process.
The suffix "ic acid" is often used to denote a carboxylic acid. "Carboxylic" refers to the presence of a carboxyl group (-COOH) in the compound, which is responsible for its acidic properties.
