About Imidazole, GR 99%+

Listed under CAS 288-32-4, Imidazole is a biological buffer available from Vaqora Chemicals (AR grade) at a purity of ≥99%. Formula C3H4N2, molecular weight 68.08 g/mol. Its systematic (IUPAC) name is 1H-imidazole. Alternative names: 1,3-Diaza-2,4-cyclopentadiene and Glyoxaline.

The material typically appears as white to pale yellow crystalline or flakes or crystals. Reported physical data include a melting point of 88-91 °C and a density of 1.03 g/cm3 at 20 °C. Store sealed in a dry, well-ventilated location away from incompatible materials. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Key uses span buffer preparation, cell culture, electrophoresis and chromatography and protein and peptide research. It is used across academic and industrial research and diagnostics and biotechnology.

Vaqora Chemicals supplies Imidazole in 25 g, 100 g, 500 g and 5 kg packs, each shipped with a Certificate of Analysis (COA), and exports worldwide.
