Description

Sodium n-Acetyl-L-Cysteinate is the sodium salt of N-acetyl-L-cysteine, a stabilized and more bioavailable derivative of the essential amino acid L-cysteine. This compound matters for its role as a powerful antioxidant and mucolytic agent, offering enhanced stability and solubility for advanced formulations. It is critically needed by manufacturers in the pharmaceutical, nutraceutical, and cosmetic industries for developing products that support respiratory health, cellular protection, and detoxification.

Application

• Pharmaceutical Active Ingredient: Core component in mucolytic medications and inhalable solutions for treating chronic respiratory conditions like COPD and cystic fibrosis.
• Nutraceutical & Dietary Supplements: Used in antioxidant formulations, liver support supplements, and products aimed at boosting glutathione levels for detoxification.
• Cosmetic & Personal Care: Incorporated into anti-aging serums, skin brightening creams, and haircare products for its antioxidant and protective properties against environmental damage.
• Research & Biochemical Reagent: Serves as a key reagent in cell culture media and biochemical research for studying oxidative stress and thiol biology.
• Veterinary Pharmaceuticals: Applied in veterinary medicine for respiratory treatments and as a detoxifying agent for livestock and pets.

Quality Control

Our Sodium n-Acetyl-L-Cysteinate is manufactured under strict quality management systems. We offer grades compliant with Pharmaceutical (USP/EP) and high-purity standards for research and nutraceutical applications. Every batch undergoes rigorous testing including assay, identification, and impurity profiling. Certificates of Analysis (COA) documenting full specifications are available upon request to ensure traceability and compliance for your regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and easily oxidized; therefore, containers must be kept tightly sealed after opening to minimize exposure to air and moisture. For long-term storage, consider using an inert atmosphere.
