In the realm of scientific research, the quality and reliability of the chemical reagents used are often the determinants of experimental success. N-alpha-(tert-Butoxycarbonyl)-L-lysine (CAS 13734-28-6), widely recognized as Boc-Lys-OH, is one such critical research chemical that finds extensive application across various scientific disciplines, particularly in peptide synthesis and organic chemistry. This article highlights why maintaining a steady supply of high-quality Boc-Lys-OH is essential for any active research laboratory.

At its core, N-alpha-(tert-Butoxycarbonyl)-L-lysine is a derivative of lysine, an amino acid. The strategic inclusion of the tert-butoxycarbonyl (Boc) group on the alpha-amino nitrogen serves as a protective shield. This protection is vital during multi-step synthesis processes, preventing the amino group from participating in unintended reactions. This controlled reactivity is fundamental for building complex molecules, especially peptides, where the precise order of amino acid addition is paramount. Researchers often buy Boc-L-lysine online with the expectation of receiving a product that guarantees this level of control and purity.

The physical characteristics of Boc-Lys-OH, typically a white powder, are standard for many organic reagents. However, its molecular formula (C11H22N2O4) and precise molecular weight (246.30 g/mol) are critical specifications for accurate laboratory work. Equally important is the purity level, with most suppliers offering it at 95% or higher. This high purity ensures that side reactions are minimized, and the desired product can be isolated with greater efficiency, saving valuable time and resources in a research setting.

The demand for Boc-Lys-OH stems from its broad utility. In peptide synthesis, it is a fundamental building block for creating therapeutic peptides, protein analogs, and research probes. Its role extends to organic synthesis, where it can be employed as a chiral synthon for constructing complex stereochemically defined molecules. Furthermore, it is an important component in the development of diagnostic reagents and in various biochemical studies investigating protein-ligand interactions or enzyme activity.

Securing research chemicals like N-alpha-(tert-Butoxycarbonyl)-L-lysine from reputable suppliers, including manufacturers in China, provides assurance of quality and consistency. A trusted supplier will provide detailed Certificates of Analysis (COAs) that document the purity, identity, and compliance with relevant standards. This diligence is crucial for reproducible scientific results and for meeting the rigorous demands of research and development projects.

In conclusion, N-alpha-(tert-Butoxycarbonyl)-L-lysine is an indispensable research chemical due to its protective functionality, structural versatility, and broad applicability. Ensuring a reliable source for this high-quality compound is a fundamental requirement for laboratories engaged in peptide synthesis, organic chemistry, and related life science research.
