Description

Etamiphyllin CAS NO 314-35-2 is a pharmaceutical-grade xanthine derivative known for its bronchodilator properties. This compound is critical for formulators and manufacturers requiring a reliable active pharmaceutical ingredient (API) for respiratory therapeutics. It is primarily utilized by the pharmaceutical industry for the development and production of medications targeting asthma, chronic obstructive pulmonary disease (COPD), and other bronchospastic conditions.

Application

• Pharmaceutical API: Primary use as an active ingredient in bronchodilator formulations for asthma and COPD treatment.
• Respiratory Therapeutics: Formulation of tablets, capsules, and injectables designed to relieve bronchospasm.
• Research & Development: A key reference standard and intermediate in pharmacological research for studying xanthine derivatives.
• Veterinary Medicine: Potential use in veterinary respiratory treatments for animals.
• Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for generic drug production.
• Clinical Trial Materials: Sourced for use in clinical studies evaluating new respiratory drug candidates.

Quality Control

Our Etamiphyllin is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity pharmaceutical standards, including identity, assay, and impurity profile verification. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support compliance with cGMP, ICH Q7 guidelines, and relevant pharmacopoeial requirements.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
