Quality Control

Our Trimethylarsine is produced and handled under stringent quality protocols to ensure batch-to-batch consistency and high purity for demanding applications. Each lot is supported by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to relevant industry standards and can provide material tailored to specific research or production-grade requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area, away from heat sources and incompatible materials. Due to its highly volatile and pyrophoric nature, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) in a certified safety cabinet. Keep container tightly sealed when not in use.
