Description

N,N,N',N'-Tetramethyl-L-Cystine is a chemically modified derivative of the amino acid L-cystine, featuring methyl groups on all four nitrogen atoms. This modification enhances its utility as a specialized building block and intermediate in advanced organic synthesis and pharmaceutical research. It is particularly valuable for researchers and manufacturers in the pharmaceutical, biotechnology, and fine chemical sectors who require high-purity, custom-tailored amino acid derivatives for drug discovery, peptide modification, and biochemical studies.

Application

• Pharmaceutical Intermediate: Serves as a key chiral building block in the synthesis of novel drug candidates and active pharmaceutical ingredients (APIs).
• Peptide Chemistry Research: Used in peptide synthesis and modification to study structure-activity relationships and enhance peptide stability.
• Biochemical Probe Development: Acts as a precursor for creating labeled compounds or probes used in biochemical assays and diagnostic research.
• Fine Chemical Synthesis: Employed as a sophisticated reagent in asymmetric synthesis and the production of complex organic molecules.
• Academic & Industrial R&D: Utilized in research laboratories for investigating new synthetic methodologies and chemical biology applications.

Quality Control

Our N,N,N',N'-Tetramethyl-L-Cystine is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity and chiral integrity, to ensure it meets the high standards required for research and development applications. A Certificate of Analysis (COA) detailing specific results for identity, purity, and related substances is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
