Quality Control

Our Otophylloside B 4'''-o-α-L-Cymaropyranoside is produced under strict quality management protocols. Each batch is subjected to comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods, to ensure it meets the stringent requirements for research-grade materials. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request to support your regulatory and research documentation needs.

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 (moisture-sensitive) nature, the container should be kept in a desiccated environment to maintain product integrity and stability.
