Quality Control

Our Cyclobutanecarboxylic Acid, 1-Cyano-3-Methylene-, Methyl Ester (9Ci) is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistent performance as a critical synthetic intermediate. Certificates of Analysis (COA) detailing purity, identity, 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, well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat, sparks, and open flame. Due to the reactive functional groups, it is recommended to store under an inert atmosphere for long-term stability and to minimize moisture uptake.
