Description
(R)-Di-tert-butyl 2-((S)-4-amino-5-tert-butoxy-5-oxopentanamido)pentanedioate is a protected dipeptide-related building block for peptide chemistry and advanced organic synthesis. Identified by CAS number 145817-20-5 and empirical formula C₂₂H₄₀N₂O₇, it has a molar mass of 444,56 g/mol. Tert-butyl ester protection on the carboxyl groups and the defined (R)/(S) stereochemistry support controlled coupling, deprotection sequences, and stereoselective assembly of glutamate-linked structures. The compound is Clear molecular-weight data aid precise weighing and stoichiometry in solution- or solid-phase protocols. Available from manufacturer Carl ROTH within a biochemicals selection, the material suits laboratories engaged in peptide mimetics, protected amino-acid derivatives, and related medicinal-chemistry intermediates. Documentation against the CAS number and formula supports inventory tracking, safety filing, and reproducibility across synthetic campaigns. Users can integrate the reagent into established protection–coupling–deprotection workflows according to their experimental design.

Questions about (R)-Di-tert-butyl 2-((S)-4-amino-5-tert-butoxy-5-oxopentanamido)pentanedioate
What is this article?
(R)-Di-tert-butyl 2-((S)-4-amino-5-tert-butoxy-5-oxopentanamido)pentanedioate 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.
