Aminoethyl methacrylate hydrochloride (AMA) is an amine based methacrylic monomer used in the production of polymers and copolymers that are utilized in a wide range of applications, including coatings, adhesives, and medical devices. It is a highly reactive monomer due to the presence of the methacrylate group, which enables it to undergo both free radical polymerization and other polymerization reactions. Due to its biocompatibility and low toxicity, it is widely used in biomedical research and as a crosslinking agent for hydrogels and other biomaterials. It is used in the synthesis of poly (2-aminoethylmethacrylate), a biocompatible cationic polymer widely used in the biomedical field.

2-Aminoethylmethacrylate hydrochloride(AMA) can be used as a precursor to synthesize:

• Homo and copolymer brushes of AMA, which can be used to tune the electrochemical properties of silicon wafers.
• Poly(3-hydroxybutyrate) based polyurethane/urea composite scaffolds for tissue engineering applications.
• Antimicrobial bacterial cellulose/poly (AMA) nanocomposites. Polymer incorporation imparts mechanical properties and antimicrobial activity to bacterial cellulose membranes.

It can also be used for the efficient functionalization of hyaluronic acid via triazine-mediated amidation.
