Quality Control

Our (R)-1-Phenylethanethiol is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chiral purity analysis by HPLC or GC, to ensure it meets the high standards required for research and synthesis. A comprehensive Certificate of Analysis (COA) detailing identity, purity (assay), enantiomeric excess (ee), and impurity profile is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at room temperature (15-25°C). Due to its highly volatile and light-sensitive nature, containers should be kept tightly sealed and opened only under an inert atmosphere when necessary to minimize oxidation and moisture uptake.
