Quality Control

Our 2-Butenoic Acid, 2-Chloro-3-Hydroxy-, Ethyl Ester is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong oxidizing agents, strong bases, and sources of ignition. Due to its ester and hydroxy functional groups, it should be considered moisture-sensitive; keep container tightly sealed when not in use.
