Product Description:
Boc - L - Pyroglutamic acid methyl ester appears as a white to off - white crystalline powder. Its chemical structure is composed of an L - pyroglutamic acid moiety, where the amino group is protected by a tert - butoxycarbonyl (BOC) group and the carboxyl group is esterified with a methyl group. This specific structure confers unique chemical properties to the compound. The BOC group acts as a safeguard, preventing the amino group from participating in unwanted reactions during various chemical procedures, and it can be removed under appropriate acidic conditions. The methyl ester group not only boosts the compound's reactivity but also has an impact on its solubility. It has poor solubility in water but dissolves well in common organic solvents like methanol, dichloromethane, and ethyl acetate.

In the fields of peptide synthesis and pharmaceutical chemistry, Boc - L - Pyroglutamic acid methyl ester is an essential building block. It is widely used in the preparation of peptides, especially those with pyroglutamic acid residues. Through coupling reactions with other amino acid derivatives, it enables the accurate construction of complex peptide sequences, playing a crucial role in the formation of peptide bonds. Moreover, its inclusion in peptide synthesis can significantly influence the properties of the final peptides, such as their stability, solubility, and biological activity. To preserve its quality and reactivity, it should be stored in a cool, dry environment, away from light and moisture.
