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