Melting Point

Solubility
From our aspect, we would suggest using dichloromethane as the solvent, other choices are
MTBE, toluene or other eithers. Water, methanol or ethanol should be avoided, because
4-META would resolve in them and the structure would change.

Application
It is usually used together with
10-MDP CAS 85590-00-7 as an adhesive in dental area.
Recommended Formulation Use
Research has found that methacrylates with both hydrophobic and hydrophilic groups, like
4-META, enhance monomer penetration into dentin pretreated with 10% citric acid and 3% ferric chloride (10-3). Examinations revealed the formation of a transitional zone of resin-reinforced dentin, termed the hybrid layer. The
4-META contains two functional groups facilitating a bridge between tooth and adhesives.
