HPLC Method for Acetaminophen (Paracetamol), Phenylephrine, Ascorbic Acid, Phenylephrine hydrochloride on Primesep S by SIELC Technologies

High Performance Liquid Chromatography (HPLC) Method for Analysis of Acetaminophen, Phenylephrine, and Ascorbic Acid

Acetaminophen, also known as Paracetamol, is a medication with the molecular formula C₈H₉NO₂. It is an over-the-counter pain killer that also reduces fever. Unlike Ibuprofen and naproxen, it is not an anti-inflammatory drug.

Phenylephrine is a common over-the-counter decongestant, but can also be used for pupil dilation and hemorrhoid treatment. It’s chemical formula is C₉H₁₃NO₂.

Ascorbic Acid is a vitamin with the molecular formula C₆H₈O₆. Typically, it is used to treat scurvy, support immune system, and preserve food. It is a white to light yellow powder that is easily dissolved in water. It can be found in a large variety of fruits and vegetables, especially in citrus.

Acetaminophen (Paracetamol), Phenylephrine, Ascorbic Acid, Phenylephrine hydrochloride can be retained and analyzed using the Primesep S stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with an ammonium acetate buffer. Detection is performed using UV.
