Quality Control

Our (E,E) Di-1-Propenyl Methyl Orthoacetate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (HPLC, GC) and spectroscopic analysis (NMR, IR), to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical quality attributes are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
