Quality Control

We maintain a rigorous quality management system to ensure batch-to-batch consistency and high purity. Our standard grade for this intermediate typically meets a purity specification of ≥97% (by HPLC), with comprehensive identity confirmation via spectroscopic methods. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting purity, residual solvents, and other critical parameters. Custom synthesis and higher purity grades (e.g., >98%, >99%) are available to meet specific project requirements under GMP or ISO 9001 guided protocols.

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 nature as an organic compound that is easily oxidized, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after the original container has been opened. Keep away from heat, sparks, and open flame.
