For chemists, formulators, and procurement specialists in the pharmaceutical and fine chemical sectors, a deep understanding of a compound's properties is fundamental to its successful application and sourcing. 2-Methylpiperazine (CAS 109-07-9) is a compound whose utility hinges on its specific characteristics. Whether you are looking to buy 2-methylpiperazine for research, development, or large-scale manufacturing, appreciating its properties will guide your procurement and usage decisions.

At its core, 2-methylpiperazine is a heterocyclic organic compound with the molecular formula C5H12N2 and a molecular weight of approximately 100.16 g/mol. Its structure features a piperazine ring substituted with a methyl group, which confers specific reactivity and physical behaviors. As an intermediate, its value lies in its ability to participate in various organic transformations.

Physically, 2-methylpiperazine is typically described as a white to yellow crystalline solid at room temperature. However, some sources may describe it as a colorless transparent liquid, which can depend on its specific isomer or ambient temperature relative to its melting point. Reliable manufacturers, such as those found in China, will often specify these details, including its density (e.g., 0.845 g/cm3) and boiling point (around 153.2 °C at 760 mmHg). Understanding these parameters is crucial for handling, storage, and process design.

Solubility is another critical property. 2-methylpiperazine exhibits good solubility in water, with a reported solubility of 78 g/100 mL at 25 °C, making it amenable to aqueous reaction systems or purification steps. This characteristic, combined with its chemical structure, makes it a valuable intermediate in synthesizing polar molecules, including pharmaceuticals like lomefloxacin.

From a safety perspective, its flash point (e.g., 45.1 °C) indicates that it is a flammable substance and requires appropriate handling precautions. When seeking to purchase 2-methylpiperazine, requesting the Material Safety Data Sheet (MSDS) from your supplier is essential for comprehensive safety information and regulatory compliance. Manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. prioritize providing detailed technical specifications and safety data to their clients, ensuring that users can effectively and safely integrate 2-methylpiperazine into their processes. Understanding these properties empowers you to source and utilize this versatile intermediate with confidence.
