The Epic™ Phenyl phase is π-basic (electron donating) and is similar in overall retention to alkyl phases. The alternate selectivity exhibited by phenyl phases is explained by the π-π interactions available through the phenyl ring. Compounds that exhibit this alternate selectivity on the Epic Phenyl phase include antibiotics such as tetracycline, moderate bases such as anesthetics, some acidic compounds such as quinoline antibiotics and nucleosides. The Epic high-density bonding technology delivers superior performance, durability and enhanced lot-to-lot reproducibility. Epic Phenyl offers a truly superior phenyl-based interaction for enhanced chromatographic performance.

Lamotrigine is an antiepileptic drug belonging in the phenyl triazine class. It is used in the treatment of both epilepsy and as a mood stabilizer for bipolar disorder. Lamotrigine related compound B also known as 2,3-dichlorobenzoic acid is a key intermediate for the antiepileptic drug Lamotrigine. It may be in found in the final product and needs to be monitored and controlled over the shelf life of the product.
The methods for assessing Lamotrigine related compound B are described in the United States Pharmacopeia1 and rely on chromatographic techniques. This application brief describes use of an Epic C18 column coupled with the LC 300 liquid chromatography system and SimplicityChrom chromatography data system (CDS).
Every decision you make in the lab affects your scientific outcomes – and that holds true for column choices. Sample solubility, chemical differences among analytes, and stationary phase chemistry are key factors in deciding which column is right for your application. The column vendor you choose must deliver the reliability, scalability, and reproducibility you need to get the most value from your method-development, quality-control, and preparative-purification processes.
Our innovative, highly efficient HPLC/UHPLC and supercritical fluid chromatography (SFC) column chemistries from ES Industries (now a PerkinElmer company) provide scientists like you with the highest quality columns, including novel chiral and achiral fluorinated phases specifically designed with pharmaceutical and environmental applications in mind. Building on ES Industries’ 40 years’ experience in column technology, we support you with applications assistance, method development guidance, and column recommendations, too.
