As a manufacturer specializing in high-quality amino acid derivatives for peptide synthesis, we understand the critical role that Fmoc-Asp(OtBu)-OH plays in the success of our clients' research and development projects. This essential building block, identified by CAS 71989-14-5, is fundamental to the Fmoc/tBu strategy in solid-phase peptide synthesis (SPPS). Our commitment is to provide researchers and pharmaceutical companies worldwide with a product that meets the most stringent purity and consistency standards.

Fmoc-Asp(OtBu)-OH, or N-Fmoc-L-aspartic acid beta-tert-butyl ester, is synthesized through carefully controlled chemical processes. The protection of both the alpha-amino group with Fmoc and the side-chain carboxyl group with a tert-butyl ester is key. This design ensures that the aspartic acid residue can be selectively incorporated into a growing peptide chain without premature reaction. The tert-butyl ester, in particular, offers stability during the repetitive cycles of Fmoc deprotection and peptide coupling, yet is readily cleaved under acidic conditions common in the final cleavage step. This makes it an ideal reagent for producing peptides intended for therapeutic or diagnostic applications.

From a manufacturing perspective, achieving high purity (typically ≥98% by HPLC) is our top priority. This involves rigorous quality control at every stage, from raw material sourcing to final product packaging. We invest in advanced analytical techniques to verify the identity, purity, and absence of critical impurities that could compromise peptide synthesis. For our clients, this means they can buy Fmoc-Asp(OtBu)-OH with confidence, knowing that it will perform reliably in their synthesis protocols.

We recognize that cost and availability are also major considerations for procurement professionals. As a manufacturer based in China, we leverage efficient production processes and economies of scale to offer competitive pricing without compromising on quality. Our robust supply chain management ensures timely delivery, whether for small-scale laboratory needs or large-scale industrial manufacturing. We encourage potential buyers to request quotes for bulk orders to take advantage of our pricing structures.

Understanding potential side reactions, such as aspartimide formation, is also important. While our product is manufactured to the highest standards to minimize such occurrences, providing clear technical information and support is part of our service. We aim to be more than just a supplier; we strive to be a partner in our clients' success, offering insights and reliable materials that facilitate groundbreaking research and the development of life-saving peptide-based products.

For those looking to purchase Fmoc-Asp(OtBu)-OH, we invite you to explore our product offerings and discover the difference that high-quality manufacturing and dedicated customer service can make. We are committed to being a trusted source for your critical peptide synthesis reagents.
