Salbutamol, also known as albuterol, is a selective β2-adrenergic receptor agonist used primarily as a bronchodilator in pharmaceutical applications. As a chemical reagent and analytical standard, it is employed in quality control, research, and development of respiratory medications to treat conditions such as asthma and chronic obstructive pulmonary disease (COPD). It functions by relaxing bronchial smooth muscles to alleviate bronchospasm. This product is supplied as a white to light beige solid with a melting point of 150-160°C, confirmed by proton NMR spectrum conforming to structure. It serves as a reference material for assays and is not intended for direct therapeutic use without further processing and regulatory approval.
