Quality Control

Our N,N'-Bis(Salicylidene)Ethylenediamine is produced under a stringent quality management system. Every batch undergoes comprehensive analytical testing, including identification by FT-IR, purity assay by HPLC, and determination of key physical parameters to ensure consistency and compliance with technical specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its light-sensitive nature and propensity to be easily oxidized, it is recommended to store the material under an inert atmosphere for long-term preservation and to minimize exposure to air upon opening.
