Quality Control

Our 1,4-Benzenedicarboxaldehyde, 2,5-Bis(Methylthio)- is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets precise customer specifications and research-grade standards. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to light and propensity for oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
