azo
Definition
- Adjective:
- Relating to or containing the azo radical: The term "azo" describes a chemical compound or group that contains the characteristic azo functional group, which consists of two nitrogen atoms double-bonded to each other and each connected to another atom or group of atoms (typically carbon). This group is central to a large class of synthetic dyes and pigments.
Usage Examples
- Adjective:
- The chemist synthesized a new azo dye for the textile industry.
- Azo compounds are often characterized by their vivid colors.
Advanced Usage
- "Azo group": The specific functional group (-N=N-) that defines azo compounds.
- The reactivity of the molecule is determined by the azo group at its center.
- "Azo linkage": Another term for the bond within the azo group.
- The stability of the dye depends on the azo linkage.
Variants and Related Words
- Azoic (adj): An older, less common term meaning without life or pertaining to the earliest geological period before evidence of life. (Note: This is a distinct term and not a direct variant of the chemical "azo," but it shares the same Greek root meaning "lifeless".)
- Azobenzene (n): A specific, well-known azo compound with the formula C₆H₅N=NC₆H₅, often used in chemical research.
- Azo dye (n): The most common application of azo compounds; a large class of synthetic dyes containing one or more azo groups.
Synonyms
- Diazo (adj): Relating to or containing a pair of nitrogen atoms. While related, "diazo" typically refers to a different functional group (-N₂⁺) and is not a perfect synonym for "azo."
Related Phrases and Terms
- Azo reduction: A chemical reaction where the azo group (-N=N-) is cleaved, typically by reducing agents.
- Azo reduction in the gut can release potentially harmful aromatic amines.
- Azo coupling: An important chemical reaction used to synthesize azo compounds, where a diazonium salt reacts with another aromatic compound.
- The brilliant red color was produced via an azo coupling reaction.
