Description

Dimethyl Dl-Aspartate is a high-purity diester derivative of the amino acid aspartic acid. This versatile chiral building block is essential for the synthesis of complex peptides, pharmaceutical intermediates, and fine chemicals. It is particularly valued in research and development for creating novel compounds in the life sciences and specialty chemical sectors.

Application

• Pharmaceutical Intermediate: A key chiral synthon for the production of active pharmaceutical ingredients (APIs) and peptide-based drugs.
• Peptide Synthesis: Used as a protected aspartic acid derivative in solid-phase and solution-phase peptide chemistry.
• Biochemical Research: Serves as a precursor or standard in metabolic pathway studies and enzyme substrate research.
• Fine Chemical Production: Employed in the synthesis of specialty surfactants, chelating agents, and flavor/fragrance compounds.
• Agrochemical Development: Acts as a building block for synthesizing novel, biologically active crop protection agents.
• Cosmetic Ingredient Synthesis: Used in the production of conditioning agents and moisturizers for personal care formulations.
