Description

Thiola-Cysteine Disulfide is a high-purity, synthetic derivative of the amino acid cysteine, specifically designed for pharmaceutical and advanced biochemical applications. This compound is valued for its role as a stable disulfide form, offering controlled reactivity and serving as a critical intermediate or active pharmaceutical ingredient (API) in therapeutic formulations. It is essential for manufacturers and R&D teams in the pharmaceutical, biotechnology, and nutraceutical sectors who require a reliable, high-quality source for drug synthesis and research.

Application

• Pharmaceutical Synthesis: Key intermediate in the production of specialized drugs, particularly those targeting conditions related to cysteine metabolism or requiring controlled redox activity.
• Active Pharmaceutical Ingredient (API): Serves as the core therapeutic agent in specific pharmaceutical formulations, leveraging its biochemical properties.
• Biochemical Research: Used as a standard or reagent in studies involving thiol-disulfide exchange, oxidative stress, and protein biochemistry.
• Nutraceutical Development: Incorporated into advanced dietary supplements where a stable, bioavailable form of cysteine is required.
• Cosmetic & Dermatological Products: Potential use in formulations aimed at skin conditioning and antioxidant protection due to its thiol-related activity.
• Reference Standard: Employed as a high-purity analytical standard in quality control laboratories for method development and validation.

Quality Control

Our Thiola-Cysteine Disulfide is manufactured under strict quality management systems to ensure it meets the high standards required for pharmaceutical and research applications. Each batch is subjected to comprehensive analytical testing, including identity confirmation, purity assay, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place 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 degradation from atmospheric moisture.
