Description

Alanine, n-(2-Mercaptoethyl)-, Dl- (8Ci) is a specialized amino acid derivative featuring a thiol (mercapto) functional group. This compound matters for its role as a versatile building block and precursor in advanced chemical synthesis, particularly where the introduction of a protected or reactive sulfur moiety is required. It is needed by researchers and manufacturers in the pharmaceutical, bioconjugation, and peptide synthesis industries for developing novel active ingredients and biochemical probes.

Application

• Pharmaceutical Intermediate: Serves as a key synthon in the research and development of new drug candidates, especially those targeting neurological or metabolic pathways.
• Peptide Modification: Used to introduce thiol groups into peptide chains for site-specific conjugation, labeling, or to create disulfide bridges that influence protein folding and stability.
• Bioconjugation Chemistry: Acts as a linker or functional handle for attaching drugs, dyes, or other molecules to proteins, antibodies, or nanoparticles.
• Biochemical Research: Employed as a substrate or inhibitor in enzymatic studies and as a precursor for synthesizing more complex cysteine analogs.
• Chelating Agent Precursor: Utilized in the synthesis of ligands designed to bind metal ions for catalytic or diagnostic applications.

Quality Control

Our Alanine, n-(2-Mercaptoethyl)-, Dl- (8Ci) is produced and tested under a rigorous quality management system. Each batch is analyzed to ensure it meets high-purity standards suitable for research and synthesis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to guarantee traceability and consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, it is recommended to handle under an inert atmosphere for long-term storage and to minimize exposure to air and moisture.
