Quality Control

Our Stigmasta-5,7,14,22,25-Pentaene-3-Ol is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via spectroscopic methods. Certificates of Analysis (COA) detailing all specifications are provided with every shipment. We adhere to cGMP principles where applicable to support our clients in research and development phases.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. Keep away from incompatible materials.
