For B2B procurement specialists in the life sciences and pharmaceutical industries, identifying reliable sources for specialized chemical reagents is a constant challenge. Fmoc-Dap(Alloc)-OH (CAS: 188970-92-5) is one such critical compound, widely utilized in peptide synthesis and organic chemistry research. This guide aims to equip buyers with the knowledge to effectively source this essential Fmoc-protected amino acid derivative.

The first step for any buyer is to clearly define their needs. Fmoc-Dap(Alloc)-OH is primarily used as a protected amino acid building block. Its dual protection strategy, with the Fmoc group on the alpha-amino position and the Alloc group on the beta-amino position, offers significant advantages in controlled peptide chain elongation. When searching for suppliers, B2B buyers should look for specifications that confirm high purity (often >98% or >99%) and enantiomeric purity, as these are crucial for successful and reproducible synthesis.

When looking to buy Fmoc-Dap(Alloc)-OH, a key consideration is the supplier's origin and manufacturing capabilities. Many global research institutions and pharmaceutical companies source fine chemicals from experienced manufacturers in China due to competitive pricing and established production infrastructure. However, it's vital to vet potential suppliers to ensure they meet quality standards and can provide necessary documentation, such as Certificates of Analysis (CoA). Comparing prices from different manufacturers is also a standard procurement practice to secure cost-effective materials.

The CAS number, 188970-92-5, is the most direct way to search for Fmoc-Dap(Alloc)-OH. Online chemical marketplaces and supplier directories will list products with this identifier. Buyers should pay attention to the packaging sizes offered, ranging from gram-scale for initial R&D to kilogram-scale for larger projects. Requesting a quote for bulk quantities is often beneficial for securing better unit prices and ensuring supply continuity.

Furthermore, a responsive and knowledgeable supplier can be a valuable partner. Features like fast order processing, reliable shipping (e.g., same-day dispatch for in-stock items), and accessible customer support are indicators of a reputable chemical provider. Understanding the logistical aspects, including international shipping and customs regulations for importing chemical reagents, is also part of a successful procurement strategy.

In essence, sourcing Fmoc-Dap(Alloc)-OH requires diligence. By focusing on purity, competitive pricing from reliable manufacturers, and efficient logistics, B2B buyers can ensure they acquire this vital peptide synthesis reagent efficiently and effectively. Always confirm product specifications and supplier reliability before placing an order.
