Description

Dl-A 3-Dimethyltyrosine CAS NO 28484-37-9 is a synthetic, non-proteinogenic amino acid derivative of tyrosine, characterized by the dimethylation of the amino group. This structural modification is of significant interest in pharmaceutical research and development, particularly for studying enzyme interactions and receptor binding where the native tyrosine moiety is involved. It serves as a critical building block and reference standard for medicinal chemists and biochemists in the synthesis of novel peptide analogs, enzyme inhibitors, and for probing biochemical pathways.

Application

• Pharmaceutical Intermediate: Key starting material or advanced intermediate in the synthesis of targeted drug candidates and active pharmaceutical ingredients (APIs).
• Biochemical Research: Used as a specialized reagent and reference standard in enzymatic studies, metabolic pathway analysis, and structure-activity relationship (SAR) investigations.
• Peptide Synthesis: Incorporated into custom peptide sequences to modulate their biological activity, stability, and receptor affinity.
• Neuroscience Research: Applied in studies related to neurotransmitter synthesis and metabolism, given its structural relationship to catecholamine precursors.
• Analytical Standard: Serves as a high-purity certified reference material (CRM) for quality control and method validation in analytical laboratories.
