Quality Control

Every batch of 2-Pentenal, 2-Methyl-4-Oxo- (9Ci) is produced and tested under strict quality management protocols to ensure consistency and reliability for your critical processes. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as purity, identity, and impurity profiles. Our quality systems are designed to support applications requiring high-purity intermediates, including those under cGMP guidelines for pharmaceutical development.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area at 2-8°C to minimize oxidation and volatility. Keep away from heat, sparks, and open flames. Due to its highly volatile and easily oxidized nature, containers must be kept sealed and handled with appropriate precautions to prevent degradation and ensure product integrity.
