HPLC Method for Analysis of Pamoic acid on Primesep B by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Pamoic acid
Pamoic acid, also known as embonic acid, is a compound used in the formation of salts, particularly pamoate salts. The pamoate salts of various drugs are often employed to enhance their solubility, stability, and overall pharmaceutical properties. Pamoic acid itself is characterized by its ability to form stable complexes with a variety of drugs, and these complexes can be more easily processed into pharmaceutical formulations. The use of pamoic acid and its salts is common in the pharmaceutical industry to improve the bioavailability and effectiveness of certain medications. The formation of pamoate salts is a strategy employed in drug development to optimize the therapeutic delivery and performance of various pharmaceutical compounds.
Pamoic acid can be retained, and analyzed using a Primesep B mixed-mode stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water, acetonitrile (MeCN), and sulfuric acid as a buffer. Detection is achieved using UV 235 nm

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.

Separation of Pamoic acid on Newcrom R1 HPLC column
May 16, 2018
Pamoic acid 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.
