In the intricate world of advanced organic synthesis, specific chemical intermediates play pivotal roles in constructing complex molecular architectures. Ethyl N-Cbz-4-Oxopyrrolidine-3-carboxylate, bearing the CAS number 51814-19-8, stands out as one such valuable compound. Its unique structural features offer a foundation for diverse synthetic transformations, making it a sought-after material for chemists engaged in cutting-edge research and development.

The molecular structure of Ethyl N-Cbz-4-Oxopyrrolidine-3-carboxylate is key to its utility. It features a central pyrrolidine ring, a five-membered nitrogen-containing heterocycle. This ring is substituted at the 4-position with a carbonyl group (oxo), rendering it a ketone. Furthermore, it has an ethyl carboxylate group at the 3-position and a benzyloxycarbonyl (Cbz) protecting group attached to the nitrogen atom at the 1-position. This combination of functional groups—a ketone, an ester, and a carbamate—endows the molecule with a rich reactivity profile.

The presence of the ketone functionality allows for nucleophilic addition reactions, reduction, or condensation, opening pathways to various hydroxylated or alkylated pyrrolidine derivatives. The ester group can undergo hydrolysis, transesterification, or reduction. The Cbz group serves as a protecting group for the nitrogen atom, which can be selectively removed under specific conditions (e.g., hydrogenolysis) to reveal a free amine for further functionalization. This strategic placement of reactive sites and protecting groups makes it an ideal synthon for building complex nitrogen-containing heterocyclic structures common in pharmaceuticals.

When professionals seek to buy Ethyl N-Cbz-4-Oxopyrrolidine-3-carboxylate, they are looking for a reliable supplier that can provide this intermediate with consistent quality. A purity of 97%+ is often a standard requirement for advanced synthesis to avoid side reactions and ensure high yields. Partnering with a knowledgeable manufacturer that can offer technical data and free samples is highly recommended. Obtaining a competitive quote from reputable suppliers, particularly those with experience in exporting, is crucial for managing project budgets.

In summary, Ethyl N-Cbz-4-Oxopyrrolidine-3-carboxylate (CAS 51814-19-8) is more than just a chemical; it's a versatile tool for the synthetic chemist. Its carefully arranged functional groups provide multiple avenues for modification, supporting the creation of novel compounds with potential applications in diverse scientific fields, especially in the development of new pharmaceuticals. Ensuring a quality supply from trusted sources is key to unlocking its full synthetic potential.
