Quality Control

Our Mercaptoacetic Acid 2-Methoxyethyl Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including assay by GC or HPLC, identity confirmation (IR), and impurity profiling to ensure it meets exacting standards for purity and consistency. A comprehensive 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, well-ventilated area away from heat, sparks, and open flame. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, it is recommended to store under an inert gas (e.g., nitrogen) and keep containers tightly sealed when not in use. Recommended storage temperature is 2-8°C for long-term stability.
