1-Benzyl-4-methyl-3-piperidinone(CAS: 32018-96-5)

1-Benzyl-4-methyl-3-piperidinone is a white crystalline solid with a molecular weight of approximately 237.31 g/mol. It has a melting point of 98-100°C and is slightly soluble in water but soluble in organic solvents. It is known for its mild reactivity towards nucleophiles. The compound is stable under normal conditions but should be stored away from moisture and heat.

1-Benzyl-4-methyl-3-piperidinone can be synthesized through a base-promoted condensation reaction between 1-benzylpiperidine and acetic anhydride, using sodium hydroxide as a catalyst. The reaction yields 1-Benzyl-4-methyl-3-piperidinone with good selectivity and high yield. The process is typically performed at room temperature or slightly elevated temperatures.

1-Benzyl-4-methyl-3-piperidinone is used in the pharmaceutical industry as a precursor for drug synthesis, in the polymer industry for the production of functional polymers, and in the chemical sensing industry for developing gas sensors. It also finds applications in semiconductor manufacturing for certain etching processes.

When handling 1-Benzyl-4-methyl-3-piperidinone, wear appropriate personal protective equipment (PPE) including gloves, goggles, and a laboratory coat. Ensure that the work is conducted in a well-ventilated area or a fume hood. Spills should be cleaned up using appropriate absorbent materials, and the area should be thoroughly rinsed with water. Refer to the Safety Data Sheet (SDS) for detailed safety information and emergency procedures.
