Description

Tulobuterol Hydrochloride CAS NO 73626-66-1 is a selective β2-adrenergic receptor agonist, a key pharmaceutical intermediate and active pharmaceutical ingredient (API). It is valued for its bronchodilatory properties, making it a critical component in the development and manufacture of respiratory medications. This compound is primarily required by pharmaceutical companies and research institutions engaged in the production of treatments for asthma, chronic obstructive pulmonary disease (COPD), and other bronchospastic conditions.

Application

• Pharmaceutical API: Primary use as the active ingredient in anti-asthmatic and bronchodilator formulations.
• Respiratory Drug Synthesis: A crucial intermediate in the synthesis of long-acting β-agonist (LABA) medications.
• Clinical Research: Used in preclinical and clinical studies for developing new respiratory therapeutics.
• Veterinary Medicine: Potential application in veterinary pharmaceuticals for treating respiratory distress in animals.
• Reference Standard: Serves as a high-purity analytical standard for quality control and regulatory testing in pharmaceutical labs.
• Formulation Development: Employed in R&D for creating various dosage forms such as tablets, patches, and inhalants.

Quality Control

Our Tulobuterol Hydrochloride 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) with each shipment, detailing key parameters such as assay, related substances, and residual solvents. Our quality commitment aligns with ICH guidelines and current Good Manufacturing Practice (cGMP) principles.

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.
