Thiazolidin-2-one

Thiazolidin-2-one (CAS 2682-49-7, formula C3H5NOS) is a sulfur- and nitrogen-containing heterocyclic compound, also referenced as 2-Thiazolidinone, 2-Oxothiazolidine, HOMT, and NSC 122613. It carries no assigned E-code. The compound belongs to the thiazolidinone family and is classified as a pharmaceutical intermediate.

In pharmaceutical synthesis, thiazolidin-2-one serves as a reactive building block for constructing biologically active molecules, including antimicrobial and enzyme-inhibitor candidates, where the thiazolidinone ring provides a scaffold for further functionalization. It also functions as a polymerization initiator, where the thiolactam nitrogen-sulfur motif participates in ring-opening or chain-transfer mechanisms to control polymer architecture.
