Clorprenaline in methanol is primarily used in pharmaceutical research and development as a reference standard or analytical reagent. It is employed in the preparation of calibration standards for analytical methods, such as HPLC or LC-MS, to ensure accurate quantification and identification of clorprenaline in various samples. This solution is also utilized in metabolic studies to understand the pharmacokinetics and pharmacodynamics of clorprenaline, a compound known for its bronchodilator properties. Additionally, it serves as a critical component in quality control processes to verify the purity and stability of clorprenaline in drug formulations.
