Quality Control

Our production of (8α,9β,13α,14β,17α,18β)-21,21-Dimethyl-22α-(Trimethylsiloxy)-29,30-Dinorgammaceran-3β-Ol Acetate adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, and spectroscopic identification (NMR, IR). A Certificate of Analysis (COA) detailing all specifications is provided with every 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 area at a 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. Keep away from strong acids and incompatible organic solvents.
