Quality Control

Our Ethyl Thioglycolate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for identity, purity, and composition. A Certificate of Analysis (COA) is provided with every shipment, detailing key parameters such as assay, specific gravity, and impurity profiles. We are committed to supplying material that meets the stringent requirements of our global B2B partners.

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 minimize exposure to air. Recommended storage temperature is 2-8°C for extended shelf life.
