Quality Control

Every batch of 2-Selenophenesulfinicacid,5-Methyl-(9Ci) is produced and controlled under a strict quality management system. We employ advanced analytical techniques including HPLC, NMR, and mass spectrometry to verify identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to ensure full traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Due to its light-sensitive and easily oxidized nature, long-term storage under an inert atmosphere (e.g., argon or nitrogen) at 2-8°C is recommended to maintain stability and purity. The container should be kept in a cool, dry, and well-ventilated area.
