Description

Arginine 2-Mercaptoethane Sulfonate CAS NO 106854-46-0 is a specialized amino acid derivative that combines the essential amino acid L-arginine with a thiol-containing sulfonate group. This unique molecular structure provides powerful antioxidant and radical-scavenging properties, making it a critical component in advanced pharmaceutical and nutraceutical formulations. It is primarily sought after by manufacturers in the pharmaceutical, cosmetic, and high-purity research sectors for its role in stabilizing sensitive compounds and protecting against oxidative degradation.

Application

• Pharmaceutical Active Ingredient: Used as a key component in injectable and oral formulations for its hepatoprotective and detoxifying effects.
• Antioxidant in Nutraceuticals: Incorporated into dietary supplements and functional foods to enhance stability and provide cellular antioxidant support.
• Cosmetic Stabilizer & Active: Employed in anti-aging serums, creams, and lotions to protect skin cells from oxidative stress and improve product shelf-life.
• Biochemical Research: Serves as a critical reagent in studying thiol-disulfide exchange reactions, oxidative pathways, and enzyme activity.
• Cell Culture Media Supplement: Used in specialized cell culture applications to mitigate oxidative damage to sensitive cell lines.
• Precursor for Synthesis: Acts as a building block for the synthesis of more complex peptides and pharmaceutical intermediates.

Quality Control

Our Arginine 2-Mercaptoethane Sulfonate is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including HPLC for purity, chiral analysis, and residual solvent testing, to ensure it meets stringent specifications for pharmaceutical and nutraceutical use. Certificates of Analysis (COA) are provided with each shipment, and we support compliance with cGMP, ICH Q7 guidelines, and relevant pharmacopoeial standards (e.g., USP, EP) upon request.

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 (e.g., nitrogen) after opening to maintain stability and purity. Keep away from strong oxidizing agents.
