Quality Control

We maintain a rigorous quality management system to ensure batch-to-batch consistency and high purity for research and development applications. Our standard grade for this intermediate typically meets a purity specification of ≥95% (by HPLC), with comprehensive identity confirmation via spectroscopic methods. A detailed Certificate of Analysis (COA) is provided with each shipment, documenting purity, identity, and impurity profile. Custom synthesis to higher purity grades (e.g., >98% or >99%) is available upon request.

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). This compound is moisture-sensitive (hygroscopic); keep the container tightly sealed under an inert atmosphere such as nitrogen or argon for long-term storage to prevent degradation.
