Quality Control

Our Oxiranecarboxylic Acid, 2-Ethyl-3,3-Dimethyl-, Methyl Ester, (-)- (9Ci) is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high enantiomeric purity. Each lot is analyzed using advanced chromatographic (HPLC, GC) and spectroscopic (NMR, IR) techniques. Certificates of Analysis (COA) detailing identity, purity, chiral excess, and impurity profiles are provided and can be tailored to meet specific customer or regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its light-sensitive nature, containers should be amber-colored or stored in light-resistant secondary packaging.
