Quality Control

Every batch of our 2-Tosylbenzaldehyde is manufactured and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the high-purity requirements for research and industrial synthesis. A detailed Certificate of Analysis (COA) is supplied with each shipment, reporting key parameters such as purity (by HPLC), identity (by IR and NMR), and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to handle under an inert atmosphere for long-term storage of opened containers. Keep away from heat, sparks, and open flame.
