Quality Control

Our Thiocystine is produced and tested under a strict quality management system. Each batch undergoes comprehensive analysis to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, chiral purity, and impurity profile. We adhere to current industry best practices suitable for research and development applications.

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 light-sensitive and easily oxidized nature, it is recommended to store the product under an inert atmosphere for long-term stability and to minimize degradation. Keep the container tightly sealed when not in use to prevent moisture absorption.
