Quality Control

Our 3-Quinolinethiol is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including identification, assay, and impurity profiling. A Certificate of Analysis (COA) detailing the specific results for purity (typically >97% by HPLC), appearance, and other critical parameters is provided with every shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

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) in a cool, dry, well-ventilated place. Due to its sensitivity to oxidation, the container should be kept sealed when not in use to minimize exposure to air.
