Quality Control

Our 2-Mercapto-4-Methoxybenzaldehyde is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high chemical purity and consistency. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

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 oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from strong oxidizing agents.
