imidazool

Imidazool is a chemical compound that belongs to the family of imidazoles, a class of heterocyclic aromatic molecules containing two nitrogen atoms in a five‑membered ring. The compound differs from typical imidazoles by the presence of a hydroxyl group attached to a carbon adjacent to one of the nitrogen atoms, giving it the suffix “‑ol.” The systematic IUPAC name is 4‑hydroxy‑1,3‑imidazolidine, although the precise nomenclature may vary depending on the substitution pattern.

The term imidazool first appeared in early synthetic chemistry literature in the 1970s as a potential intermediate for the production of pharmaceutical agents. In laboratory settings it is usually synthesized through the reduction of 4‑(hydroxymethyl)imidazole using catalytic hydrogenation or similar reducing agents. The resulting compound is a water‑soluble, crystalline solid that can be purified by recrystallization or chromatography.

Imidazool has attracted some interest as a scaffold for drug development because the imidazole ring can coordinate metal ions, and the hydroxyl functionality can participate in hydrogen bonding with biological targets. Early studies reported potential activity against certain bacterial strains, but subsequent investigations have largely focused on analogs with additional substituents rather than imidazool itself. Because of its low toxicity profile and ease of synthesis, imidazool has also been used as a model compound in educational courses on heterocyclic chemistry.

Safety data for imidazool indicate that it should be handled with standard laboratory precautions. The compound is not known to be a reproductive toxin or acute carcinogen, and it has a relatively low acute toxicity following ingestion or dermal exposure. However, as with all organic chemicals, it should be stored in a tightly sealed container away from strong oxidizers and kept out of reach of children.
