HPLC Separation of Acetaminophen, Caffeine and Pyrilamine maleate
March 2, 2018
Acetaminophen is a p-aminophenol derivative with analgesic and antipyretic activities. It has weak anti-inflammatory properties, may cause liver, blood cell, and kidney damage. It is a nonprescription medication for mild-to-moderate pain and fever. Caffeine is a Central Nervous System (CNS) stimulant. It is an unregulated and legal drug in most parts of the world. It can be found in the seeds and leaves in a number of plants native in Africa, East Asia and South America. Pyrilamine maleate is a histamine H1 antagonist with hypnotic properties. It has multiple uses such as an anesthetic and is used against allergies. Newcrom R1, a column that takes advantage of the newest technologies, does not contain embedded acidic nor basic ionizable groups and can retain Acetaminophen, Caffeine and Pyrilamine maleate. The method is UV compatible and can be used as a general approach for analyzing similar compounds.
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.

Separation of Pyrilamine maleate on Newcrom R1 HPLC column
February 16, 2018
Pyrilamine maleate 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.
