Description
(R)-2-Benzyl 1-tert-butyl 5-oxopyrrolidine-1,2-dicarboxylate is a differentially protected pyroglutamic acid derivative for peptide, peptidomimetic and heterocyclic synthesis. It features the empirical formula C₁₇H₂₁NO₅, a molar mass of 319,4 g/mol and CAS number 400626-71-3. The tert-butyl carbamate and benzyl ester combination allows orthogonal deprotection strategies around the 5-oxopyrrolidine core, while the defined (R) configuration supports stereocontrolled assembly of gamma-lactam and proline-related structures. The product is Offered by manufacturer Carl ROTH, this building block integrates into routes toward enzyme inhibitors, constrained peptides and other bioactive scaffolds that exploit the pyroglutamate motif. Reliable formula and mass data simplify reaction planning and analytical confirmation. Apply standard laboratory handling for protected amino-acid derivatives when dispensing the solid and preparing stock solutions for coupling or reduction steps.

Questions about (R)-2-Benzyl 1-tert-butyl 5-oxopyrrolidi, ne-1,2-dicarboxylate, 250 mg
What is this article?
(R)-2-Benzyl 1-tert-butyl 5-oxopyrrolidi, ne-1,2-dicarboxylate, 250 mg is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
