Methyl 2-(chloromethyl)acrylate(C₅H₇ClO₂)is a highly reactive,chlorine-containing acrylate ester.Itsα-chloromethyl group enables facile nucleophilic substitution and polymerization,making it valuable in advanced material synthesis.Below is a detailed breakdown of its applications:
1.Polymer Chemistry&Functional Materials
Reactive Monomer for Specialty Polymers:
Synthesizes cross-linked acrylic copolymers for coatings,adhesives,and hydrogels.
Introduces pendant chloromethyl groups for post-polymerization modification(e.g.,quaternization for ion-exchange resins).
Photoresists and Lithography:
Key component in chemical amplification resists(CARs)for semiconductor patterning.Reacts with photoacid generators(PAGs)to create high-resolution features.
2.Surface Modification&Grafting
Polymer Surface Functionalization:
Antimicrobial coatings(quaternary ammonium groups).
Hydrophilicity enhancement in membranes.
Anchors reactive sites onto polymers(e.g.,polyethylene,PVC)
3.Bioconjugation&Drug Delivery
Protein/Peptide Modification:
Targeted drug delivery systems.
Enzyme immobilization in biosensors.
Conjugates with biomolecules via nucleophilic substitution(e.g.,cysteine thiols or amine groups)
Crosslinker for pH/temperature-sensitive hydrogels in controlled drug release.
4.Ion-Exchange Resins&Membranes
Precursor for Functional Resins:
Synthesizes strong anion-exchange resins after amination(e.g.,with trimethylamine).
Used in water purification,nuclear waste treatment,and chromatography.
Fuel Cell Membranes:
Modifies proton-exchange membranes(e.g.,Nafion®)to enhance ion conductivity.
5.Organic Synthesis Intermediates
Building Block for Pharmaceuticals:
Intermediate for anticancer agents(e.g.,kinase inhibitors)and antibiotics.
Agrochemical Synthesis:
Precursor for herbicides and plant growth regulators via nucleophilic displacement.
6.Adhesives&Sealants
High-Strength Structural Adhesives:
Crosslinking agent in acrylic adhesives for automotive/aerospace bonding.
