Description

Fenoterol CAS NO 391234-95-0 is a selective β2-adrenergic receptor agonist belonging to the class of sympathomimetic amines. This compound is of significant commercial and research interest due to its potent bronchodilatory effects. It is primarily utilized in the pharmaceutical industry for the development and production of active pharmaceutical ingredients (APIs) targeting respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD).

Application

• Pharmaceutical API Synthesis: Key intermediate or active ingredient in the manufacture of bronchodilator medications.
• Research & Development: Used in pharmacological studies to investigate β2-adrenergic receptor mechanisms and signaling pathways.
• Reference Standard: Serves as a high-purity analytical standard for quality control and method validation in pharmaceutical laboratories.
• Formulation Development: Employed in the development of inhalation therapies, including metered-dose inhalers (MDIs) and dry powder inhalers (DPIs).
• Biochemical Research: A tool compound for studying smooth muscle relaxation and airway physiology.

Quality Control

Our Fenoterol is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling via HPLC, to ensure it meets stringent pharmaceutical-grade specifications. Certificates of Analysis (COA) detailing all test results are provided to guarantee traceability and compliance with relevant standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption.
