Used as a key intermediate in organic synthesis, particularly in the preparation of pharmaceuticals and complex natural products. Its silyl-protected hydroxyl group allows selective reactivity, making it valuable in multi-step syntheses where functional group compatibility is critical. Commonly employed in the development of steroidal analogs and bioactive molecules due to the stability and ease of deprotection of the TBS group. The ester functionality enables further transformations such as reduction to alcohols or conversion to amides, supporting its role in building molecular complexity.
