Quality Control

Our 1-Oxoisoindoline-4-Carbaldehyde is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high purity and batch-to-batch consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment. We adhere to cGMP principles where applicable to support our clients in regulated industries.

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 properties of being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from incompatible materials.
