Quality Control

Our 4'-Sulfanyl-[1,1'-Biphenyl]-4-Carboxylic Acid is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for research and development. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay purity and impurity profiles.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) to minimize oxidation of the thiol group. The container should be kept in a cool, dry, and well-ventilated area, separate from strong oxidizing agents.
