Amlodipyric acid solution is primarily used in analytical and research settings for the detection and quantification of amlodipine, a widely prescribed calcium channel blocker used to treat hypertension and angina. The solution serves as a reference standard in pharmaceutical quality control, enabling accurate calibration of analytical instruments such as HPLC (High-Performance Liquid Chromatography) and UV-Vis spectrophotometers. It is also employed in stability studies to assess the degradation products of amlodipine under various environmental conditions. Due to its well-characterized properties, the solution supports method development and validation in drug formulation analysis, ensuring consistency, purity, and efficacy of amlodipine-containing medications.
