Quality Control

Our Quercetin 3-o-β-D-(6''-p-Coumaroyl)Glucopyranosyl(1-2)-α-L-Rhamnopyranoside is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the stringent requirements for research and production. Certificates of Analysis (COA) detailing all specifications are provided and can be tailored to support regulatory submissions for pharmaceutical (GMP) or nutraceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is light-sensitive (store away from light) and hygroscopic (moisture-sensitive); therefore, the container must be kept tightly sealed in a desiccated environment to maintain stability and purity.
