Applications:

UV-Vis Spectrum of Ivermectin B1a

July 25, 2024
UV-Vis Spectrum of Ivermectin B1a. Absorption Maxima: 244 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. The spectra presented here are measured with an acidic mobile phase that has a pH of 3 or lower.

 High Performance Liquid Chromatography (HPLC) Method for Analysis of Pamoic acid, Ivermectin B1a, Pyrantel

Pamoic Acid:

  • Pamoic acid is a compound used in pharmaceuticals, particularly as a salt form.
  • Its salt, such as pamoate salts, is often used to improve the solubility and stability of certain drugs.
  • Pamoic acid is commonly used in the formulation of drugs to enhance their pharmacokinetic properties.

Ivermectin:

  • Ivermectin is an antiparasitic medication that belongs to the class of drugs called avermectins.
  • It is widely used to treat parasitic infections, including certain types of roundworm infections and scabies.
  • Ivermectin works by interfering with the nervous system of parasites, leading to their paralysis and eventual death.

Pyrantel:

  • Pyrantel is an anthelmintic or deworming medication.
  • It is commonly used to treat infections caused by roundworms and hookworms.
  • Pyrantel works by causing neuromuscular blockade in the parasites, leading to their expulsion from the digestive tract.

Pamoic Acid, Ivermectin, Pyrantel be retained, separated and analyzed using a Primesep 100 mixed-mode stationary phase column. The analysis employs an isocratic method with a simple mobile phase comprising water, acetonitrile (MeCN), and sulfuric acid as a buffer. This method allows for detection using UV 245 and 315 nm

Separation of Ivermectin B1a on Newcrom R1 HPLC column

Ivermectin B1a can be analyzed by this reverse phase (RP) HPLC method with simple conditions. The mobile phase contains an 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 particles columns available for fast UPLC applications. This liquid chromatography method is scalable and can be used for isolation 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.
