| Hazard Information | Back Directory | [Description]
6-Maleimidocaproic acid contains a maleimide group and a terminal carboxylic acid. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. | [Chemical Properties]

| [Application]
6-Maleimidocaproic acid is a sulfhydryl reactive heterobifunctional crosslinking reagent. It can be widely used probe for introducing maleimides groups into biomolecules. A probe for thiol groups in proteins. Spacer Arm: 9.4 Angstroms. Probe for thiol groups (SH-groups) in membrane proteins. | [Definition]
ChEBI: 6-Maleimidocaproic acid is a medium-chain fatty acid. It contains a maleimide group and a terminal carboxylic acid. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. The maleimide group will react with a thiol group to form a covalent bond, enabling the connection of biomolecule with a thiol. | [Synthesis]
Maleic anhydride (29.4 g, 0.3 mol) and 6-aminocaproic acid (39.35 g, 0.3 mol) were refluxed in
glacial acetic acid (900 mL) for 16 h. Acetic anhydride (30.6 g, 0.3 mol) was added dropwise over
a period of 2 hand reflux was continued for 1 h. The acetic acid was removed under vacuum at 70
°C to yield yellow syrup which solidified. The material was chromatographed over silica using
dichloromethane-methanol-acetic acid (100:5:1) affording a crystalline solid (6-Maleimidocaproic acid).
