Description

Glycylmethionine 4-Toluenesulfonate is a high-purity, protected amino acid derivative where the glycylmethionine dipeptide is stabilized as a tosylate salt. This compound is critical for providing a readily available, chemically defined building block for advanced peptide synthesis and pharmaceutical research. It is primarily utilized by R&D chemists and manufacturers in the pharmaceutical, biotechnology, and fine chemical sectors for developing novel therapeutic peptides and biochemical probes.

Application

• Pharmaceutical Intermediate: A key protected building block in the solid-phase and solution-phase synthesis of complex peptide-based drugs and APIs.
• Biochemical Research: Used in studies of peptide structure-activity relationships (SAR), metabolism, and as a standard in analytical method development.
• Prodrug Development: Serves as a precursor or modified amino acid component in the design of prodrugs to enhance bioavailability and stability.
• Fine Chemical Synthesis: Employed as a specialized reagent for introducing the Gly-Met sequence into custom peptides, flavors, or fragrances.
• Cosmetic Peptides: Potential use as a raw material in the synthesis of bioactive peptides for high-end skincare and cosmetic formulations.
