Quality Control

Every batch of 3-Penten-2-One, 4-Amino-5,5-Difluoro- (9Ci) is produced and tested under a strict quality management system. Our products undergo rigorous quality testing to ensure compliance with industry standards for research and fine chemical use. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
