For laboratories and pharmaceutical companies dedicated to advancing peptide-based drug discovery and development, the consistent availability of high-quality raw materials is non-negotiable. Fmoc-Glu(OtBu)-Ser(Psi(Me,Me)Pro)-OH, a sophisticated dipeptide building block, plays a pivotal role in these endeavors. This guide aims to assist procurement professionals and R&D scientists in understanding the key considerations when sourcing this vital chemical intermediate.

The selection of Fmoc-Glu(OtBu)-Ser(Psi(Me,Me)Pro)-OH is driven by its specific chemical properties, namely its high purity and the advantages conferred by its Fmoc protection and pseudoproline modification. These features are critical for efficient peptide synthesis, contributing to improved solubility, reduced aggregation, and enhanced yields of target peptides. When looking to buy this compound, understanding the specifications such as CAS Number 909115-33-9, molecular formula C30H36N2O8, and molecular weight 552.62 g/mol is paramount.

As a buyer, one of the primary concerns is identifying reliable suppliers and manufacturers. The global market offers numerous sources, but for critical research and development applications, consistency in product quality is key. Many international chemical companies and specialized peptide synthesis reagent providers offer Fmoc-Glu(OtBu)-Ser(Psi(Me,Me)Pro)-OH. When sourcing from China, for instance, it is beneficial to engage with manufacturers who have a proven track record in producing high-purity amino acid derivatives and intermediates.

Pricing is another significant factor for procurement. The cost of Fmoc-Glu(OtBu)-Ser(Psi(Me,Me)Pro)-OH can vary considerably based on the supplier, the quantity purchased, and the required purity level. Buyers are encouraged to request quotes from multiple suppliers, especially for larger orders, to secure the best possible price. Understanding the price per gram or kilogram is crucial for budgeting R&D projects effectively. Bulk purchase inquiries often lead to more favorable pricing structures.

Furthermore, beyond the product itself, evaluating a supplier's service offering is important. This includes the availability of technical documentation such as Certificates of Analysis (CoA), Safety Data Sheets (SDS), and lot traceability. Efficient customer support and responsive communication channels are also indicators of a trustworthy partner. For those needing custom quantities or specific packaging, direct communication with a manufacturer or their sales representative is recommended.

In summary, sourcing Fmoc-Glu(OtBu)-Ser(Psi(Me,Me)Pro)-OH requires careful consideration of product specifications, supplier reputation, and pricing. By focusing on these aspects, researchers and procurement specialists can ensure they acquire a high-quality intermediate that supports the success of their peptide synthesis projects and contributes to the development of innovative peptide-based solutions.
