Peptide synthesis is a cornerstone of modern biotechnology and pharmaceutical research, enabling the creation of therapeutic agents, diagnostic tools, and fundamental research probes. At the heart of efficient and accurate peptide assembly lies the selection of appropriate coupling reagents. Among the most effective is 1-Hydroxy-7-azabenzotriazole, commonly known as HOAt.

As a premier supplier of high-purity chemical reagents, NINGBO INNO PHARMCHEM CO.,LTD. recognizes the critical role HOAt plays in advancing peptide chemistry. HOAt is a derivative of HOBt, but with a nitrogen atom incorporated into the benzotriazole ring. This structural modification significantly enhances its efficacy as a coupling additive, particularly when paired with carbodiimide reagents like DIC or EDC, or with phosphonium and uronium-based coupling agents like HATU (which is derived from HOAt). The primary advantage of HOAt lies in its ability to dramatically increase coupling efficiency and significantly suppress racemization, especially when dealing with sterically hindered amino acids or challenging peptide sequences.

For procurement managers and R&D scientists, understanding the benefits of HOAt is crucial. When you buy HOAt, you are investing in a reagent that can lead to higher yields, cleaner reaction profiles, and ultimately, more reliable peptide products. The ability to minimize epimerization is paramount in pharmaceutical applications where the chirality of amino acids directly impacts the biological activity and safety of the final peptide drug. Our commitment as a leading manufacturer in China ensures that you receive HOAt with exceptional purity (≥99.0% by HPLC), a critical factor for reproducible results in demanding synthetic protocols.

The applications of HOAt extend beyond its direct use as a coupling additive. It serves as a fundamental building block for the synthesis of even more potent coupling reagents, such as HATU. This makes HOAt an indispensable component in the toolkit of any peptide chemist. Whether you are engaged in solid-phase peptide synthesis (SPPS) or solution-phase synthesis, incorporating HOAt into your reaction system can lead to substantial improvements in reaction speed and overall success rates. For those seeking to purchase this vital reagent, exploring the competitive price points available from reputable suppliers like NINGBO INNO PHARMCHEM CO.,LTD. is a wise step towards optimizing research budgets.

If your research involves complex peptide targets, fragment condensation, or requires the highest degree of stereochemical control, HOAt is an essential reagent to consider.
