3,4-Diacetoxystyrene Description
3,4-Diacetoxystyrene (CAS: 57142-64-0), also known as 4-vinyl-1,2-phenylene diacetate or MPACS, is a versatile aromatic monomer derived from catechol, featuring a styrene backbone with two ortho-acetoxy groups.
It is key in synthesizing functional polymers for resins, coatings, and electronic materials. Its applications extend to pharmaceuticals: as a fluorescent/linking group in anti-tumor drugs for DNA binding and imaging, structural template for anti-inflammatory and osteoporosis therapies.
3,4-Diacetoxystyrene Application
Polymer Synthesis: Monomer for catechol-based polymers in resins, adhesives, and coatings; enables controlled polymerization with deprotection to catechols for adhesion and crosslinking.
Electronic Materials: Used in photoresists and conductive polymers for OLEDs, sensors, and flexible electronics due to a styrene backbone and functionalizable groups.
Pharmaceutical Intermediates: Protected form of 3,4-dihydroxystyrene; serves as a fluorescent linker in anti-tumor conjugates for DNA binding/imaging, and a scaffold for anti-inflammatory or osteoporosis therapies.
3,4-Diacetoxystyrene
It should be kept in a cool, dry, well-ventilated place. Keep in tightly sealed containers protected from light, moisture, and electrostatic discharge. Store apart from foodstuffs and incompatibles (e.g., strong oxidants).
