Q:
What is 4-Aminobenzophenone CAS 1137-41-3?
A: 4-Aminobenzophenone is an aromatic aminoketone identified by CAS 1137-41-3 and molecular formula C₁₃H₁₁NO. It is also called p-aminobenzophenone, 4-benzoylaniline, or (4-aminophenyl)(phenyl)methanone. The amino and benzophenone groups make it a useful building block for further functionalization. -
Q:
What is 4-Aminobenzophenone mainly used for?
A: It is primarily used as a pharmaceutical intermediate and is a key starting material for the broad-spectrum anthelmintic Mebendazole. It is also used to prepare heterocycles such as 1,2,3-triazoles, benzothiazoles, pyrimidinones, and related compounds. Other applications include dyes, polymers, specialty organic synthesis, and photochemical or nonlinear-optical research. -
Q:
What grades and typical properties should be confirmed?
A: Common catalog grades are around 98% or higher, often specified as a crystalline powder. Typical properties include a melting range near 121-124 °C, a boiling point around 246 °C at reduced pressure, and solubility in alcohol and ether with more limited cold-water solubility. Confirm assay, color, moisture, related isomers, and the impurity limits required by the downstream route. -
Q:
How should 4-Aminobenzophenone be stored and handled?
A: Store in tightly closed containers in a cool, dry, ventilated area away from heat, strong oxidizers, and incompatible materials. Protect from light where the supplied grade requires it. Avoid dust generation and use appropriate PPE when handling the solid at scale.
