Quality Control

Every batch of 2-Pentenoic Acid, 3,4-Dihydroxy-2-Nitro-, -γ--Lactone (5Ci) is produced and tested under a strict quality management system. We ensure high purity and batch-to-batch consistency through advanced analytical techniques including HPLC, NMR, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your R&D and 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 (15-25°C). Due to its hygroscopic and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation. Keep away from incompatible materials.
