For research scientists and procurement managers in the pharmaceutical and biotech industries, the efficiency and success of peptide synthesis projects often hinge on the quality of the raw materials used. Among the most vital components in a chemist's toolkit is a range of protected amino acids, and Boc-L-4-Methoxyphenylalanine stands out as a particularly important building block. As a leading manufacturer and supplier, understanding its properties and applications is crucial for anyone involved in drug discovery and development.

Boc-L-4-Methoxyphenylalanine, identified by its CAS number 53267-93-9, is a protected derivative of the amino acid tyrosine. The 'Boc' group, or tert-butoxycarbonyl, serves as a protective shield for the amino group, preventing unwanted reactions during complex synthetic pathways. This protection is paramount in solid-phase peptide synthesis (SPPS) and solution-phase methods, where precise control over reaction sites is essential for building the desired peptide chain accurately.

The '4-methoxy' substitution on the phenyl ring of phenylalanine, coupled with the Boc protection and L-stereochemistry, makes this compound uniquely suited for incorporating specific structural motifs into peptides. These motifs can influence a peptide’s biological activity, stability, and pharmacokinetic properties. For instance, it is instrumental in synthesizing potent vasopressin antagonists and oxytocin antagonists, highlighting its significance in developing targeted therapeutics.

When considering where to purchase this vital intermediate, sourcing from a reputable manufacturer in China offers significant advantages. Not only can you ensure high purity, typically 97% or above, but you also gain access to competitive pricing for bulk orders. This combination of quality and cost-effectiveness is critical for research labs and manufacturing facilities managing project budgets. A dependable supplier ensures consistent batch-to-batch quality, which is non-negotiable in pharmaceutical research where reproducibility is key.

Researchers looking to buy Boc-L-4-Methoxyphenylalanine should prioritize suppliers who provide detailed specifications, safety data sheets (SDS), and certificates of analysis (CoA). These documents verify the product's purity and suitability for sensitive applications. By partnering with an experienced manufacturer, you not only secure a reliable supply of Boc-L-4-Methoxyphenylalanine but also gain a strategic advantage in accelerating your peptide-based drug development projects.

In summary, the role of Boc-L-4-Methoxyphenylalanine in modern peptide chemistry cannot be overstated. Its careful use, combined with procurement from trusted manufacturers and suppliers, is fundamental to advancing pharmaceutical research and bringing innovative peptide therapeutics to market.
