Description

L-Cysteine, Nitrate (Ester) (9Ci) is a chemically modified derivative of the essential amino acid L-Cysteine, where the nitrate ester functional group is introduced. This modification is significant as it can alter the compound's reactivity, stability, and solubility profile, making it a valuable synthetic intermediate for specialized chemical synthesis. It is primarily needed by research institutions and fine chemical manufacturers developing novel pharmaceutical actives, biochemical probes, or advanced materials where precise molecular manipulation is required.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of novel drug candidates, particularly those targeting neurological or metabolic pathways.
• Biochemical Research: Used as a specialized reagent in proteomics and enzymology studies to investigate protein structure-function relationships and enzyme mechanisms.
• Peptide Synthesis: Employed in solid-phase or solution-phase peptide synthesis to incorporate modified cysteine residues with unique properties into peptide sequences.
• Chemical Biology Tool: Acts as a precursor for creating labeled or tagged cysteine derivatives used in cellular imaging and bio-conjugation strategies.
• Fine Chemical Production: Utilized in the multi-step synthesis of complex organic molecules for agrochemicals or advanced material science applications.
