Quality Control

Our (Z)-3-Methyl-3-Pentenoic Acid Methyl Ester is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopy (IR, NMR), to verify identity, isomeric purity, and chemical composition. Certificates of Analysis (COA) documenting all critical parameters are available upon request to ensure full traceability and compliance with your project specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from incompatible materials such as strong bases and oxidizing agents. Recommended storage temperature is 2-8°C for long-term stability, although the product is typically stable at controlled room temperature for shorter periods. Keep container tightly sealed when not in use to prevent evaporation and minimize exposure to moisture.
