Quality Control

Our (E,Z) 2-Propyl-2-Pentenoic Acid Ethyl Ester is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure identity, purity, and consistency. We provide a detailed Certificate of Analysis (COA) with every shipment, documenting critical parameters such as assay, isomeric ratio, and impurity profiles. Our quality commitment ensures the material meets the stringent requirements for pharmaceutical and fine chemical applications.

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). Due to its properties as a strong acid/organic solvent and being easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, and open flames. Keep container tightly sealed when not in use to minimize loss through high volatility.
