Description

Glutathione, Oxidized is a vital disulfide compound formed from two reduced glutathione molecules, serving as a key intracellular redox buffer. Its primary commercial value lies in its role as a stable, high-purity reference standard and active ingredient for research and pharmaceutical development. This product is essential for manufacturers and R&D laboratories in the pharmaceutical, nutraceutical, and cosmetic industries, where it is used to study oxidative stress mechanisms and develop therapeutic and anti-aging formulations.

Application

• Pharmaceutical Reference Standard: Used as a certified primary standard for analytical method development and quality control testing of glutathione-based drugs and supplements.
• Biochemical Research: Critical for in vitro studies of redox biology, enzyme kinetics (e.g., glutathione peroxidase), and cellular antioxidant defense systems.
• Nutraceutical Formulation: Incorporated into high-end dietary supplements aimed at supporting liver detoxification and overall antioxidant status.
• Cosmetic & Skincare Actives: Serves as a stable active ingredient in serums and creams designed to combat oxidative skin damage and promote a brighter complexion.
• Cell Culture Supplement: Added to media to maintain redox potential and support the growth and function of certain cell lines in bioprocessing.
• Diagnostic Reagent Manufacturing: Used in the production of test kits for assessing oxidative stress markers and glutathione-related metabolic pathways.
