Quality Control

Our Mercaptoacetaldehyde is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C to minimize oxidation and polymerization. Keep away from strong oxidizing agents and bases. Due to its light-sensitive and easily oxidized nature, prolonged exposure to air, light, or ambient temperatures should be avoided.
