Sodium borohydride is a reducing agent commonly used in organic synthesis and chemical analysis. It is a white, crystalline solid that reacts with water and alcohols to generate hydrogen gas. Sodium borohydride is often employed in the reduction of carbonyl compounds, such as aldehydes and ketones, to alcohols. Its core function is to serve as a mild and selective reducing agent in various chemical reactions.

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.
