Custom Manufacturing, Project Outsourcing, your Trusted Partner from China
The field of chemistry is constantly evolving, driven by the development of new methodologies and the synthesis of increasingly complex molecules. At the heart of many of these advancements are specialty amino acids, which serve as versatile building blocks and reagents. NINGBO INNO PHARMCHEM CO.,LTD. is a key supplier of these crucial compounds, including the widely used Z-Tyr(Bzl)-OH (N-alpha-Benzyloxycarbonyl-O-benzyl-L-tyrosine), supporting innovation across various chemical disciplines.
Z-Tyr(Bzl)-OH, identified by its CAS number 16677-29-5, represents a protected derivative of the amino acid tyrosine. Its structure is characterized by a Benzyloxycarbonyl (Z) protecting group on the alpha-amino nitrogen and a Benzyl (Bzl) ether protecting group on the phenolic hydroxyl of the side chain. These protective groups are strategically employed to modulate the reactivity of the amino acid during synthetic processes, most notably in peptide synthesis. They ensure that reactions occur regioselectively, allowing for the precise construction of complex peptide chains or other sophisticated organic molecules.
The utility of specialty amino acids like Z-Tyr(Bzl)-OH extends far beyond basic peptide assembly. In advanced organic synthesis, they are invaluable as chiral starting materials for creating complex stereocenters. The ability to selectively deprotect or further functionalize the molecule at specific points makes them adaptable for a wide range of synthetic targets. For example, the benzyl ether protection on tyrosine can be removed under specific conditions, revealing a reactive hydroxyl group that can be further elaborated into various functional moieties.
NINGBO INNO PHARMCHEM CO.,LTD. is committed to providing these essential chemical building blocks with the highest standards of purity and consistency. Our Z-Tyr(Bzl)-OH typically exhibits a purity of over 98% (HPLC), ensuring that researchers and manufacturers can rely on its performance in their critical applications. This reliability is fundamental for reproducible scientific results and efficient manufacturing processes in areas such as pharmaceuticals, diagnostics, and materials science.
As a supplier of key chemical building blocks, NINGBO INNO PHARMCHEM CO.,LTD. understands the importance of accessibility and affordability. We offer competitive pricing and support for both small-scale research quantities and larger bulk orders. By providing access to high-quality Z-Tyr(Bzl)-OH and other vital specialty amino acids, we empower chemists to push the boundaries of innovation and develop the next generation of scientific advancements.
