Quality Control

Our (3-Nitrophenyl)-Propynoic Acid is produced 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 heavy metals, to ensure it meets the high standards required for research and development. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and compliance with your specifications.

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 nature, the container must be kept tightly sealed to prevent moisture absorption. Keep away from incompatible materials such as strong bases and oxidizing agents.
