Online Published on 23 January, 2024. Abstract A new, simple, rapid, selective, precise and accurate isocratic reverse-phase high-performance liquid Chromatography assay method has been developed to estimate Linezolid in tablet formulations. The separation was achieved using column Inert sustain C18 (250×4.6mm, 5μ) in the mobile phase consisting of methanol: 1% Acetic acid (50:50 v/v). The flow rate was 0.80mL/min-1, and the separated Linezolid was detected using a UV detector at 249nm. Column temperature 45°C and sample temperature ambient and injection volume 20μL. The retention time of Linezolid was noted to be 7.3 min. The method was validated as per ICH guidelines. The proposed method was found to be accurate, reproducible, and consistent.
