Quality Control

Our Oxiranecarboxylic Acid, 2,3-Dimethyl-, Ethyl Ester, trans- (9Ci) is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity assessment by HPLC, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided to guarantee consistency and support your regulatory needs.

Storage

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