Quality Control

Every batch of our 2(3H)-Furanone,3-Amino-5-Ethylidenedihydro-,[S-(E)]-(9Ci) is produced under strict quality management systems. We employ advanced analytical techniques including HPLC, chiral GC, and NMR to ensure high chemical and enantiomeric purity. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to guarantee batch-to-batch consistency for your critical R&D and scale-up processes.

Storage

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