Description

S-Allyl-L-Cysteine is a sulfur-containing amino acid derivative, a key bioactive component found in aged garlic extract. This compound matters for its significant role as a precursor to allicin and other organosulfur compounds, offering potent antioxidant and cytoprotective properties. It is primarily needed by manufacturers in the nutraceutical, pharmaceutical, and functional food industries seeking to formulate products that support cardiovascular health, detoxification, and cellular defense mechanisms.

Application

• Nutraceutical & Dietary Supplement Formulation: A core ingredient in capsules, tablets, and powders targeting antioxidant support, liver health, and detoxification.
• Functional Food & Beverage Fortification: Incorporated into health drinks, nutritional bars, and specialized food products to enhance bioactive content.
• Pharmaceutical Intermediates: Serves as a critical chiral building block and precursor in the synthesis of more complex therapeutic agents.
• Cosmeceutical Ingredients: Used in advanced skincare formulations for its antioxidant and potential anti-aging benefits.
• Research & Development: A standard compound for biochemical research, particularly in studies related to oxidative stress, sulfur metabolism, and cardiovascular models.
• Veterinary Health Products: Included in supplements for companion and livestock animals for similar health-promoting effects.

Quality Control

Our S-Allyl-L-Cysteine is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and chiral integrity, to ensure it meets high-grade specifications suitable for nutraceutical and research applications. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and compliance.

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 under an inert atmosphere after opening to maintain stability and prevent degradation.
