1. Escitalopram

Class of compounds: Drug
Nature of compounds: Basic, Hydrophobic

Application description

Escilatopram is an antidepressant medication mainly used to treat major depressive disorders. Escilatopram is a selective serotonin reuptake inhibitor. The compound is hydrophobic and basic in nature. HPLC method was developed for HPLC analysis of Escitalopram on Coresep 100 mixed-mode column. The method is robust with good peak shape for main compound. This method can be used for analysis of hydrophobic basic compounds in reversed-phase cation-exchange mode. Retention time is controlled by amount of ACN, buffer concentration and buffer pH. Method is fast, robust, reproducible, and can be used for analysis of escitalopram in various samples. Various mobile phases can be used with Coresep 100 column to accommodate different detection techniques (UV, MS, CAD, ELSD detection). Core-shell mixed-mode columns provide a great combination of unique selectivity, speed, and efficiency.

1. Escitalopram

Class of compounds: Drug
Nature of compounds: Basic, Hydrophobic

Application description

Escitalopram is an antidepressant medication mainly used for major depressive disorders. Escilatopram is a selective Serotonin reuptake inhibitor. The compound is hydrophobic and basic in nature. The HPLC method was developed for the HPLC analysis of Escitalopram on Coresep SB mixed-mode column. The method is robust with a good peak shape for the main compound. There is no interaction between residual silanols on the surface of the stationary phase and this basic hydrophobic compound. The residual silanols are shielded by a positively charged group on the surface of silica gel. This method can be used for the analysis of hydrophobic basic compounds in reversed-phase cation-exclusion mode. Various mobile phases can be used with the Coresep SB column to accommodate multiple detection techniques (UV, MS, CAD, ELSD detection). Core-shell mixed-mode columns provide great combination of unique selectivity, speed and efficiency.
