Quality Control

Every batch of Cyclopropanecarboxylic Acid, 1-Amino-2-Ethenyl-, Ethyl Ester, Hydrochloride is manufactured under a strict quality management system. We provide comprehensive analytical data to ensure the identity, purity, and consistency required for sensitive R&D and scale-up processes. A detailed Certificate of Analysis (COA) is supplied with each shipment, documenting key parameters such as assay (HPLC), chiral purity, and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which may affect stability and handling properties.
