Robust and Rugged Stability-Indicating HPLC Method for the Determination of Plerixafor and Its Related Impurities in Drug Substances.

A novel, reversed-phase high-performance liquid chromatographic method was developed and validated for the determination of related substances in Plerixafor (PLX) drug substance. PLX is an immunostimulant used to mobilize hematopoietic stem cells in cancer patients. The method is efficient for estimation of all degradation and process-related impurities.

Stability-indicating HPLC method for quantification of celecoxib and diacerein along with its impurities in capsule dosage form.

A novel stability-indicating reverse phase high performance liquid chromatography method was developed and validated for the simultaneous determination of Celecoxib (CEL) and Diacerein (DIN) and its impurities in capsule dosage form. The method was developed using L1 column with gradient using the mobile phase consist of Solution A (pH = 2.3 buffer) and Solution B (methanol and acetonitrile; 50 : 50, v/v).

Novel Validated Stability-Indicating UPLC Method for the Estimation of Naproxen and its Impurities in Bulk Drugs and Pharmaceutical Dosage Form.

A novel, reversed-phase ultra-performance liquid chromatographic method was developed and validated for the determination of related substances in Naproxen (NAP) bulk drugs and dosage forms. The related substances included degradation and process-related impurities. The method was developed using the Waters Acquity BEH C18 column using the gradient program with mobile phase A of a pH 7.
