Product Name:5-(3-Phenylprop-2-ynoyl)-1,3-dihydro-2-benzofuran-1-one
English Name:5-(3-Phenylprop-2-ynoyl)-1,3-dihydro-2-benzofuran-1-one
CAS No.:1329658-14-1
Aliases:Phenylethynyl trimellitic anhydride, 5-(3-Phenylprop-2-ynoyl)phthalide
Molecular Formula:C17H10O3
Physical Properties:White to off-white crystalline powder, melting point 150~155 °C, insoluble in water, soluble in organic solvents such as N-methylpyrrolidone and N,N-dimethylformamide.
Uses:Used as an end-capping agent for high-performance polyimide (PI) resins, broadening the processing temperature window without releasing small molecules during curing, meeting the requirements of large-area bonding. The cured product has an aromatic structure with significantly improved thermo-oxidative stability, excellent heat resistance and adhesion properties. It can also be used as an organic synthesis intermediate for producing other chemical materials.
Technical Specifications:
Appearance: white to off-white crystalline powder
Assay (HPLC): ≥98.0%
Melting point: 150~155 °C
Loss on drying: ≤0.5%
Solubility: insoluble in water, soluble in N-methylpyrrolidone, N,N-dimethylformamide and other organic solvents
