For researchers and manufacturers engaged in peptide synthesis, the selection of appropriate amino acid derivatives is paramount. These building blocks are the foundation upon which complex peptide chains are constructed, directly influencing the purity, yield, and overall success of the final product. Among these vital components, H-Asn-OtBu, or L-Asparagine tert-butyl ester, stands out as a frequently used and critical intermediate. Understanding its properties and how to procure it effectively from a reliable supplier is key.

H-Asn-OtBu, identified by its CAS number 25456-86-4, is a protected form of asparagine. The tert-butyl ester group on the carboxyl side chain offers protection during peptide coupling reactions, preventing unwanted side reactions and enhancing solubility. This protection is generally removed during the final cleavage and deprotection steps of peptide synthesis, yielding the desired peptide chain. As a specialist chemical manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. focuses on providing high-purity H-Asn-OtBu to meet the stringent demands of the pharmaceutical and biotechnology industries.

When considering where to buy H-Asn-OtBu, it is essential to look for a manufacturer that guarantees consistency in quality and a stable supply chain. Factors such as purity levels, batch-to-batch variability, and the availability of comprehensive technical documentation (like Certificates of Analysis) are crucial. For bulk purchases, engaging directly with a primary manufacturer like NINGBO INNO PHARMCHEM CO.,LTD. can offer significant advantages in terms of pricing and logistical efficiency. We understand the importance of reliable sourcing for your R&D and production timelines.

The process of peptide synthesis is intricate, involving multiple coupling and deprotection steps. The choice of protecting groups, including the tert-butyl ester in H-Asn-OtBu, plays a vital role in orthogonality and overall efficiency. By choosing a reputable supplier, you ensure that your starting materials are of the highest standard, minimizing the risk of failed synthesis batches and costly rework.
