Quality Control

Every batch of our (10α)-2α,3α,16α,20,25-Pentahydroxy-9β-Methyl-19-Norlanosta-5,23-Diene-11,22-Dione undergoes rigorous analytical testing to ensure identity, purity, and consistency. We adhere to strict in-house specifications aligned with research-grade material standards. Comprehensive Certificates of Analysis (COA) detailing purity (HPLC), identity (IR, NMR), and impurity profiles are provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, it is recommended to store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation. Keep the container tightly sealed when not in use to prevent moisture absorption.
