Quality Control

Our Methyltriphenylarsonium Iodide is manufactured under controlled conditions to ensure high chemical purity and batch-to-batch consistency. Each lot undergoes rigorous analytical testing, including identification, assay, and impurity profiling. A comprehensive Certificate of Analysis (COA) detailing purity, physical characteristics, and test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; containers must be kept tightly sealed to minimize exposure to atmospheric moisture and light to maintain stability.
