Quality Control

Our Butanoic Acid, 2-(Hydroxyimino)-3-Oxo-, Ethyl Ester, (2Z)- is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistent performance as a research-grade chemical. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to the reactive nature of oxime esters, it is recommended to store under an inert atmosphere for long-term stability and to minimize potential decomposition.
