Quality Control

Our Isodecyl Mercaptoacetate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing including assay, purity, and impurity profile determination to ensure it meets the high standards required for industrial polymerization and synthesis. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its properties of being easily oxidized and highly volatile, it is recommended to store under an inert atmosphere (e.g., nitrogen) when possible and keep containers tightly sealed to prevent evaporation and oxidation. Recommended storage temperature is 15-25°C.
