Product Description
Molecular Formula: C3H4N2
Molecular Weight: 68.08
CAS Number: 288-32-4
pKa: 7.1 1
Melting Point: 90-91 °C2
Imidazole can be used to prepare buffers in the pH range of 6.2-7.8 at 25 °C. It is also a chelator for the binding of various divalent cations. The logs of the binding constants for various divalent cations are below:
Divalent Cation Log binding constant
Ca2+ 0.1
Mn2+ 1.6
Fe2+ 3.3
Co2+ 2.4
Ni2+ 2.9
Cu2+ 4.2
Zn2+ 2.0
These values compare to an EDTA affinity constant log of 10.6 for Ca2+.3
Imidazole can be used for the elution of histidine containing proteins from divalent cation resins (Product No. P6611, His-Select™-HC Nickel affinity gel) and can also be used in reverse staining of SDS-PAGE gels for detection of proteins.4
Precautions and Disclaimer
For Laboratory Use Only. Not for drug, household or other uses.
Preparation Instructions
Imidazole is soluble in water (approximately 500 mg/ml), yielding a clear solution.
Storage/Stability
Solutions can be successfully sterilized by autoclaving, and are stable for at least 2 years at 2-8 °C, protected from light.
