Description

Danosteine is a synthetic mucolytic agent and a key pharmaceutical intermediate. This compound is valued for its role in the synthesis of active pharmaceutical ingredients (APIs) targeting respiratory conditions. It is primarily required by pharmaceutical manufacturers and research institutions engaged in drug development for chronic obstructive pulmonary disease (COPD), bronchitis, and other pulmonary disorders. Our supply ensures high purity and consistent quality for critical R&D and production processes.

Application

• Pharmaceutical Intermediate: Primary use in the synthesis of mucolytic and expectorant active pharmaceutical ingredients (APIs).
• Respiratory Drug Development: Key building block for research into new therapeutics for chronic obstructive pulmonary disease (COPD) and bronchitis.
• Biochemical Research: Used in studies investigating thiol-based mechanisms and their effects on mucus viscosity.
• Reference Standard: Serves as a high-purity analytical standard for quality control and method validation in pharmaceutical laboratories.
• Preclinical Studies: Employed in the formulation of compounds for pharmacological and toxicological evaluation.

Quality Control

Our Danosteine is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity, identity confirmation by IR and NMR, and residual solvent analysis. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to ensure traceability and compliance with your specifications.

Storage

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