4-Methylpiperidine(CAS#626-58-4)

Brief introduction
4-Methylpiperidine is an organic compound.

Quality:
- Appearance: 4-Methylpiperidine is a colorless liquid.
- Solubility: It can be soluble in many organic solvents such as ethanol, ether, and chloroform.
- Stinky odor: It has a pungent ammonia smell.

Use:
- 4-Methylpiperidine is commonly used as a catalyst and solvent in organic synthesis. It can facilitate the progress of certain chemical reactions and improve the selectivity and yield of the reaction.

Method:
- There are several ways to prepare 4-methylpiperidine. One of the commonly used methods is to obtain 4-methylpyridine by reaction of hydrogen cyanide and 1,4-dichlorobutane, followed by nucleophilic substitution reaction with acetic acid and alkaline conditions to obtain 4-methylpiperidine.

Safety Information:
- 4-Methylpiperidine has some toxicity. Contact with the skin, eyes, or inhalation of its vapors may cause irritation, burns, or other uncomfortable reactions.
- When using 4-methylpiperidine, take personal protective measures, such as wearing protective gloves, eye protection, and ensure that you operate in a well-ventilated area.
- In the event of a leak, appropriate emergency measures need to be taken, such as removing or isolating the leak quickly and disposing of it safely.
