The pharmaceutical industry constantly seeks advanced chemical building blocks that can streamline the synthesis of complex drug molecules. Boc-O-(2-bromo-Cbz)-L-Tyrosine, identified by its CAS number 47689-67-8, has emerged as a particularly versatile pharmaceutical intermediate. This protected amino acid derivative offers unique advantages for researchers and manufacturers engaged in drug discovery and development.

Characterized by its white crystalline powder appearance and a high purity assay (typically 98.5% min), Boc-O-(2-bromo-Cbz)-L-Tyrosine is a testament to precise chemical manufacturing. Its structure, featuring the tert-butyloxycarbonyl (Boc) protecting group on the alpha-amino function and the 2-bromo-benzyloxycarbonyl (2-bromo-Cbz) protecting group on the hydroxyl of L-Tyrosine, provides chemists with significant synthetic flexibility. This dual protection scheme allows for selective removal of protecting groups under different reaction conditions, a crucial aspect in multi-step organic syntheses.

The primary application of Boc-O-(2-bromo-Cbz)-L-Tyrosine is in peptide synthesis. Peptides are an increasingly important class of therapeutics, and their synthesis requires protected amino acid building blocks like this one. The 2-bromo-Cbz group offers a distinct cleavage mechanism, distinct from standard Cbz or Boc protection, providing orthogonal protection strategies that are invaluable when constructing complex peptide sequences or when other acid-labile or base-labile groups are present in the molecule. This makes it an excellent choice for researchers aiming to buy high-quality reagents for advanced peptide construction.

For pharmaceutical companies and contract research organizations (CROs), sourcing this intermediate reliably is key. Manufacturers in China are a significant source for these high-purity chemicals. When looking to buy Boc-O-(2-bromo-Cbz)-L-Tyrosine, it is advisable to partner with a supplier that emphasizes quality control, provides detailed product documentation, and offers competitive pricing. A reliable manufacturer ensures that the compound meets the stringent purity requirements necessary for drug synthesis.

The versatility of Boc-O-(2-bromo-Cbz)-L-Tyrosine also extends to its use in the synthesis of small molecule drugs and other biologically active compounds where a modified tyrosine residue is required. Its stable structure and well-defined reactivity make it an attractive intermediate for chemists developing innovative therapeutic agents. Whether for research purposes or larger-scale manufacturing, ensuring a consistent supply from a trusted supplier is paramount.

In conclusion, Boc-O-(2-bromo-Cbz)-L-Tyrosine (CAS 47689-67-8) is a highly versatile pharmaceutical intermediate due to its unique protecting groups and high purity. Its application in peptide synthesis and broader organic chemistry makes it an essential compound for drug discovery.
