imidazole
C2Technical
Definition
Meaning
A colourless, crystalline organic compound with a five-membered ring containing two nitrogen atoms.
Any of a class of organic compounds that contain this ring structure, including many biologically important molecules like histidine, histamine, and some antifungal and anthelmintic drugs.
Linguistics
Semantic Notes
Primarily used in chemistry and biochemistry. It refers both to the specific parent compound and to the entire class of derivatives. In pharmacology, it often denotes antifungal agents.

Learning
Memory Aids
Mnemonic
Imagine 'IMID' as 'I'm ID' for its chemical identity, and 'AZOLE' for its ring family – 'I'm identified as an azole.'
Conceptual Metaphor
THE BUILDING BLOCK METAPHOR: Imidazole is a fundamental 'building block' or 'scaffold' for constructing more complex biologically active molecules.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Direct phonetic transliteration 'имидазол' is correct. No false friends.
Common Mistakes
- Spelling: 'imidizole', 'immidazole'. Pronunciation: stressing the first syllable (/ˈɪmɪdəzoʊl/).

FAQ
Frequently Asked Questions
Both. The imidazole ring occurs naturally in amino acids like histidine, but many synthetic derivatives are created for pharmaceuticals.
Imidazole has two nitrogen atoms in its five-membered ring, while triazole has three. Both are classes of antifungal azoles.
Yes. In British English: /ˌɪmɪdˈeɪzəʊl/ (im-id-AY-zohl). In American English: /ˌɪmɪdˈæzoʊl/ (im-id-A-zohl).
Its ring structure can act as both a hydrogen bond donor and acceptor, and it can exist in protonated and deprotonated forms near physiological pH, making it crucial for enzyme catalysis (e.g., in histidine residues).
