CAS 22728-89-8: D-Aspartic acid, 4-methyl ester, hydrochloride (1:1)

Description: D-Aspartic acid, 4-methyl ester, hydrochloride (1:1) is a derivative of the amino acid D-aspartic acid, characterized by the presence of a methyl ester group at the 4-position of the aspartic acid backbone. This compound is typically encountered as a white crystalline powder and is soluble in water due to the presence of the hydrochloride salt form, which enhances its solubility and stability. It is known for its role in various biochemical processes, particularly in the synthesis of neurotransmitters and hormones. The hydrochloride form indicates that the compound is protonated, which can influence its reactivity and interaction with biological systems. D-Aspartic acid derivatives are often studied for their potential effects on hormone regulation, particularly in relation to testosterone synthesis. As with many amino acid derivatives, it is important to handle this compound with care, following appropriate safety protocols, as it may have specific biological activities and effects that warrant further investigation in pharmacological contexts.
