Quality Control

Our Resact is produced under strict quality management systems to ensure batch-to-batch consistency and high purity for research applications. Each lot undergoes comprehensive analytical characterization, including HPLC for purity determination and mass spectrometry for identity confirmation. Certificates of Analysis (COA) detailing all test results are available upon request to support your regulatory and research documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dry environment. This product is hygroscopic (moisture-sensitive). Allow the vial to equilibrate to room temperature before opening to minimize moisture uptake. For long-term storage, consider under an inert atmosphere.
