Peptide synthesis is a cornerstone of modern biotechnology and pharmaceutical research. The efficiency and success of this process heavily rely on the quality and specific properties of the amino acid building blocks used. Among these, protected amino acid derivatives play a crucial role, allowing for controlled elongation of peptide chains and preventing unwanted side reactions. One such vital component is H-Glu(OtBu)-OMe·HCl (CAS: 16948-36-0).

H-Glu(OtBu)-OMe·HCl, also known as 5-O-tert-butyl 1-O-methyl (2R)-2-aminopentanedioate hydrochloride, offers specific advantages in peptide synthesis. The tert-butyl (OtBu) protecting group on the side chain of glutamic acid is particularly useful. It is stable under many common peptide coupling conditions but can be readily removed under acidic conditions, typically using trifluoroacetic acid (TFA), which is a standard deprotection step in solid-phase peptide synthesis (SPPS). The methyl ester on the alpha-carboxyl group also provides a degree of protection during initial coupling steps.

For researchers and procurement managers looking to buy this essential reagent, understanding its role is key. When you purchase H-Glu(OtBu)-OMe·HCl from a reputable manufacturer, you are investing in the reliability of your synthesis. The consistent purity of this amino acid derivative ensures predictable reaction outcomes, minimizing the need for complex purification steps later in the process. This translates to significant time and cost savings, especially when scaling up production or conducting extensive research projects.

Many pharmaceutical and biotech companies rely on specialized chemical suppliers in China for their raw materials. Sourcing H-Glu(OtBu)-OMe·HCl from a trusted manufacturer in China can offer a compelling combination of high quality and competitive pricing. Companies that specialize in amino acid derivatives and peptide reagents are well-equipped to meet the demands for high-purity products, offering them for sale with detailed certificates of analysis. When you inquire about the price, consider the overall value proposition, including supply chain reliability and technical support.

The strategic use of protected amino acids like H-Glu(OtBu)-OMe·HCl allows chemists to meticulously control peptide synthesis. Whether you are developing novel therapeutics, diagnostic tools, or cosmetic peptides, the quality of your starting materials directly impacts the final product. Therefore, identifying a reliable supplier for H-Glu(OtBu)-OMe·HCl (CAS: 16948-36-0) is a critical step for any research team aiming for excellence. Consider reaching out to established manufacturers for quotes and samples to ensure you are partnering with the best for your peptide synthesis needs.
