N-Methylformamide (NMF), identified by its CAS number 123-39-7, is a secondary amide that holds significant interest in the chemical industry due to its distinct properties and utility in synthesis. Understanding its molecular structure, physical characteristics, and common preparation methods is essential for researchers and procurement professionals seeking to utilize this versatile compound. As a dedicated chemical manufacturer, we aim to provide insight into the foundational chemistry of NMF.

At a molecular level, N-Methylformamide (CH3NHCHO) features a central amide group connecting a methyl group to a formyl group. This structure imparts significant polarity to the molecule, classifying it as a polar aprotic solvent. Key physical properties include its appearance as a colorless liquid, a characteristic fishy or ammoniacal odor, and miscibility with water. Its melting point of -4 °C and boiling point of 182.6 °C further define its behavior and suitability for various reaction conditions. The stability of the N-C(O) bond, influenced by resonance, also contributes to its unique chemical characteristics.

The preparation of N-Methylformamide typically involves straightforward chemical reactions. A common industrial method is the reaction between methylamine and methyl formate. This process yields NMF along with methanol as a byproduct. An alternative, though less common, route involves transamidation, where formamide reacts with methylamine to produce N-Methylformamide and ammonia. These synthesis methods are well-established, allowing manufacturers to produce NMF efficiently and at scale.

For those looking to buy N-Methylformamide, knowledge of its properties is crucial for selecting the appropriate applications. Its use as a solvent in organic synthesis and in industrial settings like oil refining stems directly from its polarity and solvency power. When sourcing, understanding these intrinsic chemical properties helps ensure that the NMF procured will perform as expected in your specific processes. For businesses in need of this chemical, engaging with a reliable manufacturer ensures access to high-purity NMF at competitive prices, backed by technical expertise.

In essence, N-Methylformamide is a compound defined by its polarity, reactivity, and efficient synthesis pathways. Its well-understood chemical profile makes it a valuable reagent and solvent for a wide range of applications, from laboratory research to industrial manufacturing. By partnering with a reputable supplier, you can ensure you have access to the quality NMF necessary for your chemical endeavors.
