Quality Control

Our Phthalen-1-Ylidene)Malononitrile is produced under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure high purity and batch-to-batch consistency. We provide comprehensive Certificates of Analysis (COA) with every shipment, detailing all relevant specifications. Our quality system is designed to meet the stringent requirements of GMP and ISO standards for chemical manufacturing.

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 sensitivity to light and propensity for oxidation, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flames.
