For researchers and chemists deeply involved in peptide synthesis, the selection of high-quality building blocks is paramount. Among the diverse array of unnatural amino acids, Fmoc-D-2-Bromophenylalanine stands out as a critical component, particularly for advanced Solid-Phase Peptide Synthesis (SPPS). This article delves into the significance of this specific amino acid derivative, its unique properties, and why sourcing it from a reputable manufacturer is essential for successful research and development projects.

Fmoc-D-2-Bromophenylalanine, identified by CAS number 220497-79-0, is a derivative of phenylalanine that incorporates two key features: the Fmoc (9-fluorenylmethoxycarbonyl) protecting group and a bromine atom substituted at the ortho position of the phenyl ring. The Fmoc group is widely favored in SPPS due to its mild deprotection conditions, typically using a weak base like piperidine. This orthogonality allows for selective removal of the protecting group without affecting other sensitive functional groups within the peptide chain or the resin linkage. This characteristic greatly simplifies the synthesis process and minimizes unwanted side reactions, leading to higher yields and purer final products.

The presence of the bromine atom is another critical aspect of Fmoc-D-2-Bromophenylalanine. Halogen substituents on aromatic rings often increase reactivity, making this amino acid a versatile building block for further chemical modifications. This is particularly valuable in medicinal chemistry, where chemists aim to fine-tune the properties of peptide-based drug candidates. The bromine atom can serve as a handle for various cross-coupling reactions, enabling the introduction of diverse functional groups or the creation of complex molecular architectures. This capability is essential for developing targeted therapies and improving the efficacy and pharmacokinetic profiles of potential drugs.

When considering the purchase of Fmoc-D-2-Bromophenylalanine, the purity of the compound is a significant factor. Reputable suppliers, such as NINGBO INNO PHARMCHEM CO.,LTD., typically offer this reagent with a purity of 97% or higher. This high purity is crucial because impurities can lead to side reactions, incomplete coupling, and difficulties in purifying the final peptide. For any serious researcher or development team, investing in high-quality materials is a strategic decision that ensures reproducible results and accelerates project timelines. Purchasing from a trusted manufacturer in China provides access to these essential materials at competitive prices, facilitating both small-scale research and larger development initiatives.

The applications of Fmoc-D-2-Bromophenylalanine extend across several key areas within the life sciences and pharmaceutical industries. Its primary use is in the synthesis of peptides, including those with complex sequences or modified residues. It is also instrumental in drug discovery, where peptide mimetics and peptide-based therapeutics are increasingly important. By incorporating unnatural amino acids like Fmoc-D-2-Bromophenylalanine, researchers can design peptides with enhanced stability against enzymatic degradation, improved binding affinities, or novel biological activities. For those looking to buy or obtain a quote for this essential reagent, engaging with experienced suppliers is the first step towards successful peptide development.

In summary, Fmoc-D-2-Bromophenylalanine (CAS: 220497-79-0) is an indispensable tool for modern peptide synthesis. Its combination of Fmoc protection and a reactive bromine substituent makes it highly valuable for constructing intricate peptide structures and for applications in medicinal chemistry and drug discovery. Ensuring a reliable supply chain by partnering with experienced manufacturers and suppliers is key to achieving optimal results in your research endeavors.
