Quality Control

Our [S-(E)]-7-Heneicosen-10-Ol is manufactured under strict quality management systems. Every batch undergoes comprehensive analytical testing, including chiral purity assessment by HPLC, to ensure identity, strength, and composition. A detailed Certificate of Analysis (COA) documenting purity, enantiomeric excess, and impurity profiles is provided with each shipment to guarantee batch-to-batch consistency and compliance with your research or production specifications.

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). This material is moisture-sensitive (hygroscopic); keep the container tightly sealed under an inert atmosphere such as nitrogen or argon to prevent oxidation and maintain product integrity.
