Quality Control

Our 2-Pentenal, 3-Hydroxy-4-Oxo- (9Ci) is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatographic purity assays and structural confirmation, to ensure it meets the stringent requirements of research and development applications. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, identity, and impurity profile.

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). This compound is light-sensitive (store away from light) and may be hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed under an inert atmosphere if specified. Keep away from strong oxidizing agents, strong acids, and strong bases.
