Quality Control

Our Methylammonium Tetrafluoroborate is manufactured under strict quality management protocols to ensure batch-to-batch consistency and high purity, which is critical for sensitive applications like perovskite research. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, impurity profiles, and moisture content. Our quality commitment aligns with the stringent requirements of research and development in advanced material science.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed and may require storage under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation to prevent degradation.
