Formamidinium iodide fai

Manufactured by Merck Group

Sourced in United States

Formamidinium iodide (FAI) is a chemical compound commonly used in laboratory settings. It is a crystalline solid that serves as a precursor material for various applications. The core function of FAI is to provide the necessary formamidinium and iodide ions for research and experimental purposes, without further interpretation or extrapolation on its intended use.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
