Boc-Lys-OH, chemically known as N-alpha-tert-Butoxycarbonyl-L-lysine, is a fundamental chiral building block with widespread applications, especially in peptide synthesis and organic chemistry. As a protected amino acid derivative, it offers specific advantages for controlled chemical reactions, making it an indispensable component for researchers and manufacturers in the pharmaceutical, biotech, and fine chemical industries.

Understanding the properties of Boc-Lys-OH is crucial for its effective utilization. It typically presents as a white to off-white powder, with a molecular weight of 246.30 g/mol and a melting point around 205°C (with decomposition). The presence of the tert-butyloxycarbonyl (Boc) group on the alpha-amino nitrogen serves as a temporary protecting group, which can be selectively removed under mild acidic conditions, allowing for controlled coupling reactions. This feature is central to its utility in Solid-Phase Peptide Synthesis (SPPS), where it enables the sequential addition of amino acids to a solid support.

The primary application of Boc-Lys-OH lies in peptide synthesis, where it is a key reagent for incorporating lysine residues into peptide chains. Lysine's side chain, with its terminal amino group, is often utilized for further functionalization, such as conjugation to other molecules or incorporation into peptide-based therapeutics that require specific charge or binding properties. Beyond peptides, Boc-Lys-OH also serves as a valuable intermediate in the synthesis of various complex organic molecules and pharmaceuticals where precise stereochemistry and functional group manipulation are required.

For those looking to buy Boc-Lys-OH, sourcing from a reliable Boc-Lys-OH manufacturer is essential. Key considerations include product purity, availability, and consistent supply. Reputable suppliers will provide detailed specifications, including CAS number (13734-28-6) and purity levels confirmed by analytical techniques like HPLC. Whether you need small quantities for research or larger volumes for industrial production, partnering with a trusted Boc-Lys-OH supplier ensures the quality necessary for successful outcomes.

The competitive landscape means that exploring options for Boc-amino acid bulk purchase can lead to significant cost efficiencies. Many manufacturers, particularly those based in China, offer competitive pricing and robust supply chains capable of meeting diverse demand. When evaluating potential suppliers, it’s advisable to inquire about their production capabilities, quality control processes, and any available technical support. This due diligence will help you secure a dependable source of high-quality Boc-Lys-OH.

In summary, Boc-Lys-OH is a vital intermediate for advanced chemical synthesis. By understanding its properties and applications, and by strategically sourcing from a reputable manufacturer, organizations can effectively integrate this essential building block into their research and production workflows, ensuring both quality and cost-effectiveness.
