Description

Carbocysteine-Lysine is a synthetic amino acid derivative combining the mucolytic properties of carbocysteine with the essential amino acid lysine. This compound is valued for its role as an active pharmaceutical ingredient (API) in the formulation of respiratory therapeutics. It is primarily utilized by pharmaceutical manufacturers and research institutions developing treatments for chronic obstructive pulmonary disease (COPD), bronchitis, and other conditions involving excessive mucus viscosity. Our supply ensures high purity and batch-to-batch consistency critical for pharmaceutical development and manufacturing.

Application

• Pharmaceutical API: Primary use as the active ingredient in prescription and over-the-counter (OTC) mucolytic and expectorant medications.
• Respiratory Therapeutics: Formulation of syrups, tablets, and effervescent granules for treating chronic bronchitis, sinusitis, and COPD.
• Veterinary Medicine: Component in veterinary pharmaceuticals for managing respiratory conditions in animals.
• Clinical Research: Standard reference material for pharmacokinetic, pharmacodynamic, and stability studies.
• Advanced Drug Delivery Systems: Research into novel formulations such as controlled-release tablets or inhalation powders.
• Biochemical Research: Study of sulfur-containing amino acid metabolism and mucin regulation pathways.

Quality Control

Our Carbocysteine-Lysine is manufactured under strict quality management systems. Each batch is tested to meet stringent specifications for pharmaceutical-grade materials, with analytical methods including HPLC, IR spectroscopy, and titration. A comprehensive Certificate of Analysis (COA) is provided with every shipment, detailing purity, impurity profiles, and residual solvents. We support compliance with major pharmacopoeial standards (e.g., EP, USP) and regulatory frameworks including ICH Q7 and GMP guidelines.

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). This product is hygroscopic (moisture-sensitive) and must be kept in original packaging or a desiccated environment to prevent degradation. Keep away from incompatible materials.
