Description

Pirbuterol is a selective β-2 adrenergic receptor agonist, a key pharmaceutical intermediate and active ingredient. Its primary commercial value lies in its bronchodilatory properties, making it essential for respiratory therapeutics. This compound is critical for manufacturers in the pharmaceutical industry developing treatments for asthma, chronic obstructive pulmonary disease (COPD), and other bronchospastic conditions. We supply high-purity Pirbuterol CAS NO 38677-81-5 to support global research, development, and production needs.

Application

• Pharmaceutical Active Ingredient (API): Primary use as the active component in bronchodilator medications.
• Respiratory Drug Formulation: Formulation of metered-dose inhalers (MDIs), dry powder inhalers (DPIs), and nebulizer solutions.
• Research & Development: Biochemical research targeting β-2 adrenergic receptors and pulmonary pharmacology studies.
• Generic Drug Manufacturing: Production of generic versions of bronchodilator drugs.
• Veterinary Pharmaceuticals: Potential use in veterinary medicine for treating respiratory conditions in animals.
• Reference Standard: Serves as a high-purity analytical reference standard for quality control laboratories.

Quality Control

Our Pirbuterol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical applications. We provide comprehensive Certificates of Analysis (COA) detailing purity, identity, and impurity profiles. Our quality commitment aligns with cGMP (Current Good Manufacturing Practice) principles, and specifications can be tailored to meet USP (United States Pharmacopeia) or other relevant pharmacopeial standards upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider using desiccants.
