Abstract
A simple isocratic liquid chromatographic method was developed for the determination of abacavir from its related substances and assay for the first time. This method involves the usage of C18 (Intertsil octadecyl silaneβ3V, 150 mmΓ4.6 mm, 5 ΞΌm) column. The method was validated over the range of 0.002β0.1 mg/mL for chloro impurity, 0.005β0.1 mg/mL for amino impurity and pyrimidine impurity, and 0.005β0.2 mg/mL for abacavir. The mobile phase consists of a mixture of 10 mM ammonium acetate buffer and ACN in the ratio of 90Β :Β 10. The flow rate was set at 1.0 mL/min with UV detection monitored at 214 nm. The drug substance was subjected to stress conditions of hydrolysis, oxidation, photolysis, and thermal degradation. The developed method was validated for linearity, range, precision, accuracy, and specificity. This method can be conveniently used in a quality control laboratory for routine analysis of both related substances and assay.
