Description

Tulobuterol Hydrochloride CAS NO 73575-62-9 is a selective β2-adrenergic receptor agonist, primarily utilized as a key active pharmaceutical ingredient (API) in the formulation of bronchodilator medications. Its primary commercial value lies in providing effective relief for respiratory conditions by relaxing airway muscles, making it a critical component for pharmaceutical manufacturers. This compound is essential for producers of asthma treatments, chronic obstructive pulmonary disease (COPD) therapies, and other respiratory pharmaceuticals requiring a reliable and potent bronchodilating agent.

Application

• Primary Active Pharmaceutical Ingredient (API) in bronchodilator medications for asthma and COPD.
• Formulation component in transdermal patches for controlled, long-acting relief of bronchospasm.
• Used in the development of pediatric respiratory treatments due to its specific pharmacological profile.
• Key intermediate in advanced pharmaceutical research for next-generation respiratory therapeutics.
• Essential raw material for the production of anti-asthmatic tablets, capsules, and syrups.
• Utilized in clinical research and reference standard preparation for analytical testing.

Quality Control

Our Tulobuterol Hydrochloride is manufactured under strict quality management systems, ensuring it meets the rigorous standards required for pharmaceutical applications. Each batch is tested against comprehensive specifications, including identity, purity, and impurity profiles, to guarantee consistency and efficacy. Certificates of Analysis (COA) are provided with every shipment, documenting compliance with relevant pharmacopeial guidelines (such as USP/EP) and internal specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can affect stability and potency.
