methyl phenol
Definition
Noun 1. A chemical compound: Methyl phenol is any of three toxic, colorless, isomeric phenols. These compounds are derived from coal tar or wood tar and are used primarily as disinfectants and antiseptics.
Usage
- Methyl phenol is a technical term used in chemistry, industrial manufacturing, and medicine.
- It refers specifically to the isomers cresol (o-cresol, m-cresol, p-cresol).
- The term is most commonly encountered in scientific literature, safety data sheets, or historical contexts describing disinfectants.
Examples
- In a scientific context: "The mixture contained methyl phenol, which accounted for its strong antiseptic properties."
- In an industrial/historical context: "Early disinfectants often relied on crude preparations containing methyl phenol derived from coal tar."
Advanced Usage
- The term methyl phenol is synonymous with the common name cresol. In most modern contexts, "cresol" is the preferred term.
- These compounds are also known by the generic name lysol when referring to certain disinfectant solutions, although Lysol is a trademarked brand.
