N-epsilon-(tert-Butoxycarbonyl)-L-lysine

Description:

N-epsilon-(tert-Butoxycarbonyl)-L-lysine, commonly referred to as Boc-Lysine, is a derivative of the amino acid lysine, characterized by the presence of a tert-butoxycarbonyl (Boc) protecting group on the epsilon amino group of the lysine side chain. This modification enhances the stability of the amino acid during chemical reactions, particularly in peptide synthesis, by preventing unwanted reactions at the amino group. Boc-Lysine is typically a white to off-white crystalline solid, soluble in organic solvents such as dichloromethane and dimethylformamide, but less soluble in water. The compound is widely used in organic synthesis and biochemistry, particularly in the preparation of peptides and proteins, due to its ability to facilitate selective deprotection under mild acidic conditions. Its molecular structure includes a primary amine, a carboxylic acid, and a hydrophobic tert-butyl group, which influences its reactivity and solubility. As with many amino acid derivatives, it is important to handle Boc-Lysine with care, following appropriate safety protocols in a laboratory setting.

NEpsilon-Boc-L-lysine

Controlled Product

CAS: 2418-95-3

Applications Nε-Boc-D-lysine is an N-Boc-protected form of L-Lysine (L468895). L-Lysine is an essential amino acid for humans, with a suggested intake of 5-8 grams per day. L-Lysine can be found in a variety of food, such as eggs and quinoa, but is also mass produced by microbial fermentation. L-Lysine is also used as therapy to treat recurrent herpes simplex infections.
