Access the UV-Vis Spectrum SIELC Library

If you are looking for optimized HPLC method to analyze Acetazolamide check our HPLC Applications library

UV/Vis.: λmax: 202, 262 nm

For optimal results in HPLC analysis, it is recommended to measure absorbance at a wavelength that matches the absorption maximum of the compound(s) being analyzed. The UV spectrum shown can assist in selecting an appropriate wavelength for your analysis. Please note that certain mobile phases and buffers may block wavelengths below 230 nm, rendering absorbance measurement at these wavelengths ineffective. If detection below 230 nm is required, it is recommended to use acetonitrile and water as low UV-transparent mobile phases, with phosphoric acid and its salts, sulfuric acid, and TFA as buffers.
For some compounds, the UV-Vis Spectrum is affected by the pH of the mobile phase. This compound was diluted in a mixture of water and acetonitrile. The method was done with a mixture of water and acetonitrile.

Separation of Acetazolamide on Newcrom R1 HPLC column

Separation of Acetazolamide on Newcrom C18 HPLC column

Acetazolamide is a drug that can treat glaucoma, epilepsy, mountain sickness, periodic paralysis, idiopathic intracranial hypertension, and heart failure. It is a diuretic as well, which makes it effective for mountain sickness. Acetazolamide can be analyzed by this reverse phase (RP) HPLC method with simple conditions. The mobile phase contains acetonitrile (MeCN), water, and phosphoric acid. For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid. Smaller 3 µm particle columns are available for fast UPLC applications. This liquid chromatography method is scalable and can be used for isolation of impurities in preparative separation. It also suitable for pharmacokinetics.

Application Column

Newcrom R1

The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.
