Quality Control

Our 2-Hydroxy-2,4-Pentadienoic Acid is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the stringent requirements for use as a chemical intermediate. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available for every shipment upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated place. Maintain storage temperature between 2°C and 8°C for long-term stability. Keep away from strong oxidizing agents.
