Quality Control

Our production of Anhydrideof3B,28-Diacetoxy-21,22-Secoloup-18-Ene-21,22-Dioicacid adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for research applications. All materials are characterized using advanced analytical techniques including NMR, HPLC, and MS. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation 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 (typically 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.
