In order to accurately determine valsartan (API), this work aims to build a straightforward and exact UV spectroscopic approach. To improve sensitivity and accuracy, the procedure entails methodically optimizing experimental parameters, including solvent choice and wavelength selection. The produced stock solutions were tested for absorbance at 249 nm using a UV spectrophotometer. With %RSD values below 2% for both intra- and inter-day, the devised approach was determined to be quite accurate. At each additional concentration, the approach was shown to be accurate, yielding good drug recoveries ranging from 98 to 101%. The process was validated for linearity, specificity, accuracy, precision and limit of detection (LoD) and limit of quantification (LoQ) as per International Council of Harmonization (ICH) criteria. Its dependability for quantitative analysis of valsartan in pharmaceutical formulations was demonstrated. This UV spectroscopic approach offers a cost-effective and efficient alternative for routine quality control in pharmaceutical industries.
