Quality Control

Our 3-(Phenylthio)Acrylic Acid is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and tests for residual solvents and moisture. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to ensure traceability and compliance with your research or production requirements.

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). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
