Description

Di-Boc-Dl-Cystathionine is a protected derivative of the sulfur-containing amino acid cystathionine, widely used as a key synthetic intermediate in organic and peptide chemistry. Its primary value lies in providing a stable, reactive building block for the controlled synthesis of complex molecules, particularly in pharmaceutical research and development. This high-purity intermediate is essential for scientists and manufacturers in the pharmaceutical, biotechnology, and advanced chemical synthesis sectors who require reliable, high-quality raw materials for producing active pharmaceutical ingredients (APIs) and novel biochemical probes.

Application

• Pharmaceutical Intermediate: A critical building block in the synthesis of novel drug candidates, particularly those targeting metabolic pathways or requiring sulfur-containing amino acid motifs.
• Peptide Synthesis: Used in solid-phase and solution-phase peptide synthesis to incorporate protected cystathionine residues into peptide chains for research and therapeutic applications.
• Biochemical Research: Serves as a precursor or standard in studies related to transsulfuration pathways, homocysteine metabolism, and related enzymatic processes.
• Protecting Group Chemistry: The di-tert-butoxycarbonyl (Boc) groups provide orthogonal protection, making it valuable for multi-step synthetic sequences where selective deprotection is required.
• Reference Standard: Utilized as a certified reference material (CRM) in analytical laboratories for method development and quality control of related compounds.
