For procurement professionals in the chemical and pharmaceutical industries, identifying and securing reliable sources for critical raw materials is a constant challenge. Fmoc-Lys(Boc)-OH, a vital building block in peptide synthesis, is one such compound. Its importance in creating complex peptides for research and therapeutic applications means that sourcing decisions have a direct impact on project timelines and outcomes. This guide, from the perspective of a seasoned supplier and manufacturer, aims to equip procurement managers with the knowledge to effectively source high-purity Fmoc-Lys(Boc)-OH.

The primary function of Fmoc-Lys(Boc)-OH is to serve as a protected amino acid derivative in Solid-Phase Peptide Synthesis (SPPS). The N-alpha-Fmoc group allows for sequential coupling, while the N-epsilon-Boc group protects the side-chain amino group of lysine. This orthogonal protection strategy is crucial for building peptides with precision. When deciding where to buy this material, several factors are critical. Firstly, purity is paramount. For most applications, particularly in pharmaceutical development, a purity of 99% or higher is essential to avoid side reactions and ensure the integrity of the final peptide product. Procurement managers should always request and scrutinize the Certificate of Analysis (CoA) for each batch, looking for detailed information on HPLC purity and residual solvents.

Secondly, reliability of supply is key. For ongoing research projects or scaled-up manufacturing, a consistent supply chain is indispensable. Partnering with a manufacturer in China that has a robust production capacity and efficient logistics network can provide the assurance of timely deliveries. This is especially important for materials like Fmoc-Lys(Boc)-OH, which are fundamental to many synthesis processes. Understanding the supplier's capacity to handle both R&D quantities and bulk orders is crucial for long-term planning.

Thirdly, competitive price and transparent pricing structures are important considerations. While cost is always a factor, it should not come at the expense of quality or reliability. Procurement managers should seek suppliers who offer fair pricing for high-purity materials and are willing to provide bulk discounts or custom quotes. For example, when you request a quote for a larger quantity, you can often secure a more favorable price.

The CAS number for Fmoc-Lys(Boc)-OH is 71989-26-9. Using this identifier when searching for suppliers will ensure you are comparing the correct product. It's also beneficial to work with suppliers who offer excellent technical support and can answer questions regarding the product's specifications, handling, and storage.
