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.

Application

• Primary Active Pharmaceutical Ingredient (API) in bronchodilator medications.
• Key intermediate in the synthesis of advanced respiratory therapeutics.
• Research and development of novel β-2 adrenergic agonists.
• Reference standard for analytical method development and quality control in pharmaceutical labs.
• Formulation studies for inhalers, nebulizers, and other pulmonary drug delivery systems.

Quality Control

Our Pirbuterol is produced under strict quality management systems. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency, meeting the stringent requirements for pharmaceutical intermediates. Certificates of Analysis (COA) detailing specifications such as assay, related substances, and residual solvents are provided with each shipment to support your regulatory and quality assurance needs.

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.
