For researchers and chemists engaged in the intricate field of peptide synthesis, the selection of high-quality building blocks is paramount. Among these vital components, Fmoc-Glu(OtBu)-Ser(Psi(Me,Me)Pro)-OH stands out as a key dipeptide derivative, facilitating the creation of complex and stable peptide chains. Understanding its properties and applications can significantly enhance experimental outcomes and streamline the drug development process.

Fmoc-Glu(OtBu)-Ser(Psi(Me,Me)Pro)-OH is characterized by its specific structure, which incorporates the Fmoc (9-fluorenylmethoxycarbonyl) protecting group. This group is widely favored in solid-phase peptide synthesis (SPPS) due to its orthogonal cleavage conditions, allowing for selective removal without affecting other sensitive functional groups within the growing peptide chain. The inclusion of the tert-butyl ester (OtBu) on the glutamic acid residue and the pseudoproline moiety on the serine residue contribute to improved solubility and conformational stability of the resulting peptides.

The utility of this dipeptide extends across various research areas. In medicinal chemistry, it plays a crucial role in the design of peptide-based therapeutics. These peptide drugs often target specific biological pathways, offering novel treatment strategies for a range of diseases. The enhanced stability and solubility provided by this building block are critical for improving the pharmacokinetic properties of these potential drugs, making them more viable for in vivo applications.

For procurement managers and R&D scientists looking to buy Fmoc-Glu(OtBu)-Ser(Psi(Me,Me)Pro)-OH, partnering with a reputable manufacturer is essential. Identifying a reliable supplier ensures consistent product quality, timely delivery, and competitive pricing, especially for bulk purchases. Many leading chemical suppliers offer this compound, with pricing varying based on quantity and purity. When seeking a manufacturer in China, verifying their quality control processes and adherence to international standards is advisable.

When considering the purchase of Fmoc-Glu(OtBu)-Ser(Psi(Me,Me)Pro)-OH, it's important to look for specifications detailing purity levels, molecular weight, and associated CAS numbers.
