Quality Control

Every batch of Z-Sar-Oh is subjected to rigorous analytical testing to ensure it meets the high-purity standards required for synthetic applications. Our quality assurance protocol includes identity confirmation, chiral purity verification, and quantification of organic and elemental impurities. A comprehensive Certificate of Analysis (COA) detailing purity (typically ≥98% by HPLC), specific rotation, and residual solvent levels is provided with each shipment to guarantee traceability and consistency.

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 nature, the container must be kept tightly sealed in a dry environment to prevent moisture absorption, which can affect stability and handling properties.
