Quality Control

Our Tetra-n-Butylammonium Dichloroaurate is manufactured under strict quality protocols. Each batch undergoes comprehensive analytical testing to ensure high chemical purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your R&D and production quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and stored in a dark environment to maintain stability and purity. Handle and store under an inert atmosphere for long-term storage.
