Sodium triacetoxyborohydride(Cas 56553-60-7) Usage


Sodium triacetoxyborohydride (STAB) is a mild, selective, and frequently used reducing agent for reductive amination transformations.


Sodium triacetoxyborohydride is a versatile reducing agent widely used in organic synthesis, particularly for reductive amination of aldehydes and ketones to primary, secondary, and tertiary amines. This white crystalline solid is more stable and selective compared to other hydride reagents, making it valuable in complex molecule synthesis. Sodium triacetoxyborohydride is known for its mild reactivity, which allows for selective reductions in the presence of other functional groups without over-reduction.

Use of sodium triacetoxyborohydride in the synthesis of nitroxide biradicals

, Journal of the Chemical Society, Perkin Transactions 1, Issue 23, 2002

A family of nitroxide biradicals was synthesized for the purpose of creating terminal groups with high relaxivity for linkage to dendrimers for use as targeted MR contrast agents for articular cartilage. The structure of the nitroxide biradicals strongly influenced their MR relaxivities. The addition of a carbon atom between the nitroxyl rings and the bridging nitrogen increased the relaxivity of the nitroxide biradical by ∼14% over what was expected by doubling the relaxivity of the monomeric nitroxide.
