Quality Control

Every batch of Cyclopentanecarboxylic Acid, 2-Amino-4-Ethenyl-, (1R,2S,4S)-Rel- (9Ci) is produced and tested under strict quality management systems to ensure identity, purity, and stereochemical integrity. Our products undergo rigorous analytical characterization, including chiral HPLC, NMR, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing purity, enantiomeric excess, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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.
