For scientists and procurement managers in the chemical and pharmaceutical industries, acquiring high-quality building blocks is essential for successful synthesis. Boc-O-(2-bromo-Cbz)-L-Tyrosine (CAS 47689-67-8) is a specialized protected amino acid that finds significant application in complex organic synthesis, particularly for peptide chemistry and pharmaceutical intermediate production. Understanding where and how to buy this compound ensures access to the purity and reliability needed for critical projects.

Boc-O-(2-bromo-Cbz)-L-Tyrosine is typically supplied as a white crystalline powder with a guaranteed high purity, often specified as 98.5% minimum assay. This high purity is crucial for its role as an intermediate, minimizing side reactions and ensuring the integrity of the final synthesized product. When looking to purchase this chemical, it is important to verify the supplier’s commitment to quality control and their ability to provide comprehensive documentation, such as certificates of analysis.

As a protected derivative of L-Tyrosine, this compound offers unique synthetic advantages. The presence of the Boc (tert-butyloxycarbonyl) group on the alpha-amino nitrogen and the 2-bromo-Cbz (2-bromo-benzyloxycarbonyl) group on the phenolic hydroxyl allows for selective protection and deprotection strategies. This makes it particularly useful in solid-phase peptide synthesis (SPPS) and other complex synthetic routes where orthogonality of protecting groups is vital for efficient chain elongation and minimal by-product formation.

When considering where to buy Boc-O-(2-bromo-Cbz)-L-Tyrosine, a primary avenue is to look towards established chemical manufacturers and suppliers. China has become a leading global source for fine chemicals and pharmaceutical intermediates, offering competitive pricing and high-quality products. By directly contacting manufacturers in China, companies can often secure better pricing and ensure a more direct and reliable supply chain. This approach is beneficial for both small-scale research needs and large-scale manufacturing requirements.

The decision to buy from a specific supplier should also involve assessing their responsiveness to inquiries, their capacity to handle orders, and their logistics capabilities. For a specialized intermediate like Boc-O-(2-bromo-Cbz)-L-Tyrosine, working with a supplier that understands the needs of the pharmaceutical and chemical research sectors is invaluable. They can provide insights into product applications, offer technical support, and facilitate smooth transactions.

In conclusion, for those seeking to buy Boc-O-(2-bromo-Cbz)-L-Tyrosine (CAS 47689-67-8), focusing on quality, purity, and reliable sourcing is paramount. Partnering with reputable manufacturers, particularly those based in China who specialize in pharmaceutical intermediates, can provide access to this essential chemical at competitive prices, supporting the advancement of your synthetic chemistry projects.
