HBr.H2N-O-(CH2)5-COOH CAS: 448954-98-1, also known as 6-Aminohexanoic acid hydrobromide, is a dual-purpose chemical used in bioconjugation and protein modification. It has an amino group for reacting with carboxylic acids and a carboxylic acid group for binding to amines. A five-unit ethylene glycol chain enhances solubility and reach. It’s often used to link proteins to surfaces, like in biosensors, or to add spacers between biomolecules. This white-to-off-white powder dissolves in polar solvents like water and DMSO.
