Quality Control

Our 1-Methoxy-3-Methylene-2-Pentanone is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopy (IR, NMR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters 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, well-ventilated area at a controlled room temperature (15-25°C/59-77°F). Due to its highly volatile nature, keep away from heat, sparks, and open flame. Ensure containers are kept upright and sealed when not in use to prevent evaporation and maintain purity.
