In the intricate world of peptide synthesis, precision and purity are paramount. For researchers and chemists aiming to create complex peptide structures with specific functionalities, the choice of building blocks can make all the difference. Among these crucial components are Fmoc-protected amino acid derivatives, particularly those that introduce post-translational modifications like phosphorylation. Fmoc-O-(benzylphospho)-L-threonine, identified by its CAS number 175291-56-2, stands out as a prime example of such an advanced intermediate.

This specialized derivative of L-threonine is designed to seamlessly integrate into solid-phase peptide synthesis (SPPS) workflows. The phenylmethoxycarbonyl (Fmoc) protecting group is a widely adopted standard in SPPS due to its stability under coupling conditions and its facile removal under mild basic conditions, which is critical for preserving the integrity of the growing peptide chain. What sets Fmoc-O-(benzylphospho)-L-threonine apart is the strategic incorporation of a benzylphosphoryl group. This modification is key for researchers looking to synthesize phosphopeptides – peptides that mimic the naturally occurring phosphorylated state of proteins. Phosphorylation is a fundamental regulatory mechanism in cellular signaling, protein-protein interactions, and enzyme activity. Therefore, the ability to accurately synthesize phosphopeptides is indispensable for understanding these complex biological processes and for developing targeted therapeutics.

When you buy Fmoc-O-(benzylphospho)-L-threonine, you are investing in a tool that can unlock new avenues in drug discovery. Its application extends to creating phosphopeptide libraries, which are invaluable for screening potential drug candidates, identifying biomarkers, and elucidating disease pathways. For example, in cancer research, aberrant protein phosphorylation is a common hallmark, and synthesized phosphopeptides can serve as research tools or even as therapeutic agents themselves. As a premier manufacturer, providing high-purity chemical intermediates is our core mission. We understand that researchers need materials with guaranteed quality to ensure reliable experimental outcomes.

Sourcing from a reputable supplier in China like us ensures that you receive Fmoc-O-(benzylphospho)-L-threonine that meets stringent purity standards, often exceeding 98% by HPLC. This level of purity is crucial to avoid side reactions and ensure the final peptide product is as intended. When considering your procurement needs, look for suppliers who provide comprehensive documentation, such as Certificates of Analysis (CoA), which detail the product's specifications and quality parameters. This diligence in sourcing is a critical step for any procurement manager or R&D scientist.

The demand for such specialized building blocks is growing as the field of peptide therapeutics and diagnostics continues to expand. Whether you are working on developing new enzyme inhibitors, signaling pathway modulators, or diagnostic probes, Fmoc-O-(benzylphospho)-L-threonine (CAS 175291-56-2) is a valuable asset. To secure a consistent supply and competitive price for your ongoing projects, it is advisable to establish a relationship with a dependable chemical supplier. Inquire about bulk quantities and custom packaging options to optimize your purchasing strategy. By partnering with an experienced chemical supplier, you can ensure timely delivery and consistent product quality, allowing your research and development efforts to progress without interruption.
