Sodium hydride is widely used as a strong base in organic synthesis, particularly in deprotonation reactions to generate carbanions. It is employed in the production of pharmaceuticals, where it facilitates the formation of active pharmaceutical ingredients by enabling key chemical transformations. In the polymer industry, it acts as a catalyst or initiator in the polymerization of certain monomers. Additionally, sodium hydride is utilized in the preparation of specialty chemicals, such as reducing agents and intermediates for fine chemicals. Its ability to release hydrogen gas upon reaction with water also makes it useful in hydrogen storage and generation applications. However, its highly reactive nature requires careful handling and storage under inert conditions.
