Product Description:

L-Alanine ethyl ester hydrochloride is a white to off-white crystalline powder. It is the ethyl ester derivative of the natural amino acid L-alanine, stabilized as its hydrochloride salt. This form enhances its solubility in organic solvents and improves its stability for handling and storage. This compound is primarily used as a chiral building block in the synthesis of pharmaceuticals and bioactive peptides. Its protected amino and carboxyl groups make it a versatile intermediate for peptide coupling reactions. It is particularly valuable in the production of various drugs and fine chemicals where the stereochemistry of the L-alanine moiety is crucial for biological activity. As a derivative of a proteinogenic amino acid, it also finds applications in biochemical research and as a precursor for more complex amino acid derivatives. It should be stored in a cool, dry place, and handled with appropriate personal protective equipment as it may cause irritation to the skin, eyes, and respiratory system.
