Description

Dl-Lysine Acetylsalicylate CAS NO 62952-06-1 is a lysine salt of acetylsalicylic acid, combining the anti-inflammatory and analgesic properties of aspirin with the amino acid lysine to enhance solubility and bioavailability. This compound is significant for its improved gastrointestinal tolerance profile compared to pure acetylsalicylic acid, making it a valuable active pharmaceutical ingredient (API). It is primarily needed by pharmaceutical manufacturers for formulating analgesic, anti-inflammatory, and antipyretic medications, as well as by research institutions developing novel therapeutic formulations.

Application

• Pharmaceutical API: Core ingredient in analgesic and anti-inflammatory tablet, capsule, and powder formulations.
• Cardiovascular Health Products: Used in low-dose formulations for antiplatelet therapy and cardiovascular risk management.
• Soluble Drug Formulations: Leveraged in effervescent tablets, sachets, and injectable solutions due to its enhanced solubility.
• Veterinary Medicine: Employed in anti-inflammatory and pain relief treatments for animals.
• Research & Development: Serves as a key intermediate or reference standard in pharmacological and pharmacokinetic studies.
• Nutraceutical Blends: Incorporated into specialized dietary supplements targeting inflammation and pain management.

Quality Control

Our Dl-Lysine Acetylsalicylate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical applications. Certificates of Analysis (COA) documenting identity, purity, and impurity profiles are provided with every shipment. We adhere to cGMP principles and can support compliance with major pharmacopoeial standards (e.g., USP, EP, JP) upon request.

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 opening to prevent moisture absorption and degradation.
