Quality Control

Every batch of our 1-Methylcyclopropane-1-Carboxylic Acid is produced and tested under a strict quality management system. We provide comprehensive analytical data to ensure the product meets the high-purity standards required for sensitive synthetic applications. A detailed Certificate of Analysis (COA) including purity assay and impurity profile is available for each lot upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere after opening to prevent degradation. Recommended long-term storage temperature is 2-8°C.
