O-tert-Butyl-L-serine Methyl Ester Hydrochloride

Product Overview

O-tert-Butyl-L-serine Methyl Ester Hydrochloride is a highly specialized protected amino acid derivative designed for use in complex organic synthesis and peptide chemistry. As a key building block, this compound features a tert-butyl protection group on the hydroxyl side chain of L-serine, providing exceptional stability during various chemical transformations. Our manufacturing process ensures consistent quality and high purity, making it an ideal choice for research laboratories and industrial pharmaceutical production facilities requiring reliable raw materials.

This hydrochloride salt form offers improved solubility and handling characteristics compared to the free base, facilitating smoother integration into multi-step synthesis routes. We adhere to strict quality control protocols to guarantee that every batch meets the rigorous demands of modern medicinal chemistry and process development.

Chemical Properties and Stability

The tert-butyl ether protection on the serine side chain is robust under many basic and nucleophilic conditions, allowing chemists to perform reactions at the amine or carboxyl termini without affecting the side chain functionality. This selective protection strategy is essential for constructing complex peptide sequences where orthogonality of protecting groups is required. The methyl ester functionality provides a convenient handle for further modification or deprotection under mild hydrolytic conditions.

With a defined boiling point and flash point, this material exhibits stable physical properties suitable for standard laboratory storage and handling procedures. The hydrochloride salt ensures the amine group remains protonated, preventing unwanted side reactions such as racemization or self-condensation during storage and transport.

Industrial Applications

This protected amino acid ester is widely utilized across several high-value sectors within the life sciences industry. Primary applications include:

• Peptide Synthesis: Serving as a fundamental building block for the solid-phase and solution-phase synthesis of therapeutic peptides.
• Pharmaceutical Intermediates: Acting as a crucial precursor in the manufacturing of active pharmaceutical ingredients (APIs) targeting various disease states.
• Chemical Biology Research: Employed in the development of probes and labeled compounds for studying protein interactions and enzymatic activities.
• Custom Organic Synthesis: Utilized by contract research organizations for creating novel compound libraries and specialized molecular structures.

Technical Specifications

Storage and Handling

To maintain optimal stability and purity, O-tert-Butyl-L-serine Methyl Ester Hydrochloride should be stored in a cool, dry environment at temperatures between 0 and 5 degrees Celsius. Containers must remain tightly closed to prevent moisture absorption, which could lead to hydrolysis of the ester or degradation of the protecting group. We recommend storing the material in a dedicated chemical dispenser within a ventilated area away from incompatible substances such as strong oxidizing agents.

Our packaging options include standard 25 kg drums, with flexibility to accommodate custom packaging requirements based on specific client logistics and volume needs. Each shipment is accompanied by a comprehensive Certificate of Analysis (COA) to verify compliance with stated specifications.
