Understanding the precise chemical profile of key intermediates is fundamental for successful synthesis in the pharmaceutical and chemical industries. Boc-Glu-OH, scientifically known as N-Boc-L-glutamic acid (CAS 2419-94-5), is one such compound, playing a crucial role in peptide synthesis and various organic transformations. As a leading manufacturer, we aim to provide clarity on its essential characteristics and synthetic utility.
Boc-Glu-OH is an alpha-amino acid derivative where the alpha-amino group is protected by a tert-butoxycarbonyl (Boc) group. This Boc protection is acid-labile, meaning it can be readily removed under acidic conditions, a key feature enabling its use in stepwise synthesis. The molecule also possesses a free alpha-carboxyl group and a gamma-carboxyl group on the side chain, both of which are available for further reactions or can be protected as needed for specific synthetic routes.
The chemical structure of Boc-Glu-OH imparts specific properties that are highly valued in synthetic chemistry. Its molecular weight is approximately 247.25 g/mol. Typically presented as a white powder, its melting point with decomposition is often cited around 110-113 °C. The purity of Boc-Glu-OH is a critical parameter for its application, with manufacturers generally offering grades of 98% or higher, confirmed by analytical methods like Thin-Layer Chromatography (TLC). This high purity is essential for ensuring the fidelity of peptide sequences and the efficiency of subsequent reactions.
The primary application of Boc-Glu-OH is in solid-phase peptide synthesis (SPPS), a method widely adopted for producing peptides for research, diagnostics, and therapeutics. In this context, Boc-Glu-OH is coupled to a growing peptide chain attached to a solid support. After coupling, the Boc group is removed using an acid (like trifluoroacetic acid or HCl) to expose the alpha-amino group for the next amino acid addition. The side-chain carboxyl group of glutamic acid may also require protection depending on the desired peptide structure.
Beyond peptide synthesis, Boc-Glu-OH can serve as a valuable building block in the synthesis of various organic molecules and pharmaceuticals. Its bifunctional nature—having both protected amino and free carboxyl groups—allows for diverse chemical modifications. Researchers often buy Boc-Glu-OH from specialized manufacturers who can guarantee batch-to-batch consistency and supply chain reliability.
For professionals seeking to buy Boc-Glu-OH, understanding these chemical characteristics is key to selecting the right supplier. A reliable manufacturer will not only provide high-purity material but also technical support and transparent pricing. We are dedicated to being that trusted source for your synthetic needs, offering high-quality Boc-Glu-OH to support your critical projects.
