Description

n-(2,4-Dinitrophenyl)-L-Alanine is a specialized amino acid derivative characterized by the presence of a dinitrophenyl (DNP) group, which serves as a key chromophore and reactive handle. This compound matters for its role as a critical intermediate and analytical standard in advanced biochemical research and synthesis. It is primarily needed by pharmaceutical R&D teams, agrochemical manufacturers, and academic laboratories working on enzyme inhibition studies, hapten conjugation for antibody production, and the development of novel peptide-based materials.

Application

• Pharmaceutical Intermediate: Serves as a key building block in the synthesis of more complex molecules for drug discovery programs.
• Biochemical Research: Used in enzyme studies and as a hapten for generating antibodies against modified amino acids or peptides.
• Agrochemical Development: Acts as a precursor in the research and synthesis of novel herbicides or plant growth regulators.
• Analytical Standard: Employed as a high-purity reference standard in HPLC, LC-MS, and other chromatographic methods for quality control and method validation.
• Peptide Chemistry: Utilized to introduce the dinitrophenyl label into peptides for tracking, purification, or studying protein interactions.
• Material Science Research: Investigated for the development of specialty polymers or functionalized surfaces with unique optical or chemical properties.
