    —— Product Detail ——


    Product Overview

    N-Acetyl-DL-alanine is an acetylated amino acid derivative with the molecular formula C₅H₉NO₃ and a molecular weight of 131.13 g/mol. This white to off-white crystalline powder is a valuable building block in peptide synthesis and biochemical research, featuring the N-acetylated form of DL-alanine. The acetylation of the amino group provides protection during peptide synthesis and can also modulate the biological properties of alanine-containing compounds. The compound is used in studies of amino acid metabolism, as a substrate for enzymatic reactions, and as a building block for the synthesis of bioactive peptides and peptidomimetics. Its racemic nature makes it useful for studying stereochemical effects.

    Synthetic Process

    N-Acetyl-DL-alanine is synthesized through the following routes:

    • Acetylation of DL-alanine: DL-Alanine is reacted with acetic anhydride or acetyl chloride in the presence of a base to selectively acetylate the amino group.

    • Purification: The crude product is purified by recrystallization from water or ethanol.

    Mechanism of Action / Application Principles

    • Peptide Synthesis: Serves as a building block for introducing N-acetyl-DL-alanine residues into peptide sequences.

    • Biochemical Research: Used in studies of amino acid metabolism and enzymatic reactions.

    • Pharmaceutical Research: Used in the synthesis of bioactive compounds and peptide-based drugs.
