Product Name:4,4'-Dinitrodiphenylmethane
English Name:4,4'-Dinitrodiphenylmethane
CAS No.:1817-74-9
Aliases:Bis(4-nitrophenyl)methane, 4,4'-Dinitrodiphenyl methane
Molecular Formula:C13H10N2O4
Physical Properties:Yellow crystalline powder. Melting point 183-186°C. Slightly soluble in ethanol and ether, insoluble in water. It may burn in the presence of open flame or high heat, and decomposes upon heating releasing nitrogen oxide gases.
Uses:Used as an organic synthesis intermediate, mainly for catalytic hydrogenation reduction to produce 4,4'-diaminodiphenylmethane (MDA), which is further used in the synthesis of diphenylmethane diisocyanate (MDI) and polyurethane materials. It is also used in the synthesis of dyes, pharmaceuticals, and fine chemicals.
Technical Specifications:
Purity: 98%
Appearance: yellow crystalline powder
Melting point: 183-186°C
Loss on drying: ≤0.5%
Storage: keep sealed in a cool, dry place
