Quality Control

Our Bis(3-Aminophenyl)Acetylene is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets the high standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C) under an inert atmosphere (e.g., nitrogen or argon) due to its sensitivity to oxidation. Keep away from heat, sparks, and open flame.
