Description

L-Cystine S,S-Dioxide is a chemically modified derivative of the amino acid cystine, characterized by the oxidation of its disulfide bond to form two sulfone groups. This specific oxidation state is significant for research into oxidative stress mechanisms, protein structure-function studies, and as a potential synthetic intermediate. It is primarily utilized by researchers and developers in the pharmaceutical, biochemical research, and nutraceutical sectors.

Application

• Biochemical Research: Used as a model compound to study the effects of oxidative modification on protein structure, stability, and function.
• Pharmaceutical Intermediates: Serves as a key building block or precursor in the synthesis of more complex molecules for drug discovery and development.
• Reference Standard: Employed as an analytical standard in chromatography (HPLC, LC-MS) for method development and quality control of related compounds.
• Nutritional Science Studies: Investigated for its role and behavior in metabolic pathways under oxidative conditions.
• Cosmetic Ingredient Research: Explored for potential applications in formulations targeting skin conditioning or antioxidant properties.

Quality Control

Our L-Cystine S,S-Dioxide is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided, typically including data from HPLC, IR, and specific rotation tests. We support research and development with reliable, high-purity materials.

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 in a dry environment to prevent absorption of moisture.
