Fmoc-Glu-OtBu, identified by its CAS number 84793-07-7, is a fundamental protected amino acid that plays a pivotal role in modern peptide chemistry. As an integral part of the Fmoc strategy for peptide synthesis, its reliable supply and consistent quality are vital for researchers and manufacturers. This article delves into the key properties and applications of Fmoc-Glu-OtBu, highlighting why it remains a sought-after chemical intermediate.
Chemical Profile of Fmoc-Glu-OtBu
The chemical structure of Fmoc-Glu-OtBu combines L-glutamic acid with two key protecting groups: the base-labile N-terminal Fmoc group and the acid-labile tert-butyl ester on the gamma-carboxyl group. Its molecular formula is C24H27NO6, and its molecular weight is approximately 425.47. Typically supplied as a solid, it is crucial that the material meets stringent purity standards, often 98% by HPLC, to ensure successful coupling and minimal unwanted side reactions during peptide chain elongation. Understanding these specifications is key for any procurement manager or R&D scientist sourcing this compound.
Applications in Peptide Synthesis and Beyond
The primary application of Fmoc-Glu-OtBu is in solid-phase peptide synthesis (SPPS), where it serves as a protected building block for incorporating glutamic acid residues into peptide sequences. The tert-butyl ester protection on the side chain prevents unwanted reactions during peptide coupling and deprotection cycles. Following the assembly of the desired peptide chain, this protecting group can be readily removed under acidic conditions, revealing the free carboxylic acid functionality.
Beyond standard peptide synthesis, Fmoc-Glu-OtBu finds use in:
