Product Description

Product Name	Imidazole (1H-Imidazole) CAS 288-32-4 \| EC No. 206-019-2 Synonyms: glyoxaline, 1,3-diazole
Formula / MW	C₃H₄N₂ / 68.08
Structure
Product Type	Five-membered aromatic heterocycle with nitrogens at the 1,3-positions; readily N-alkylated — the base raw material for azole antifungals, imidazole fungicides and epoxy curing agents.
Specification	Appearance: white to pale yellow crystals Assay: ≥ 99.0% Moisture: ≤ 0.50% Melting point 88–91 °C; boiling point 256 °C; flash point 145 °C (closed cup, literature) Typical values; the batch COA governs.
Applications	Pharmaceuticals: azole antifungals — via α-(2,4-dichlorophenyl)-1H-imidazole-1-ethanol to miconazole and econazole; also clotrimazole and ketoconazole Agrochemicals: imidazole fungicides such as prochloraz and imazalil Synthesis reagents: reacts with triphosgene to give N,N'-carbonyldiimidazole (CDI) Epoxy resins: curing agent and accelerator for laminates and adhesives Biotech: buffer (pH 6.2–7.8) and elution agent for His-tagged protein IMAC purification
Packing & Storage	Typically 25 kg fiber drums or kraft bags with PE liner; pack size per order. Hygroscopic — keep tightly closed, dry, cool and away from acids and oxidizers.

FAQ

What is imidazole?	Imidazole (CAS 288-32-4, C₃H₄N₂, MW 68.08) is a five-membered aromatic ring with nitrogens at the 1,3-positions — a base raw material for pharmaceuticals, agrochemicals, epoxy curing and biochemistry.
Imidazole vs pyrazole — what's the difference?	Same formula, different isomers: imidazole has 1,3-nitrogens and is more basic; pyrazole has adjacent 1,2-nitrogens (CAS 288-13-1). Always check the CAS number.
Is imidazole used for triazole fungicides?	No. Triazole fungicides (tebuconazole, propiconazole) are made from 1,2,4-triazole. Imidazole is used for imidazole fungicides such as prochloraz and imazalil.
Can you provide COA, SDS and samples?	Yes. Batch COA and SDS with every shipment; samples on request.
