For chemists, researchers, and material scientists, a thorough understanding of a compound's chemical properties and synthesis is fundamental to its effective utilization. NINGBO INNO PHARMCHEM CO.,LTD. offers insights into 3,5-Dimethylpyrazole (CAS 67-51-6), detailing its molecular structure, synthesis methods, and key chemical characteristics that drive its diverse applications.

3,5-Dimethylpyrazole, with the molecular formula C5H8N2 and a molecular weight of 96.13 g/mol, features a five-membered pyrazole ring. This heterocyclic aromatic ring contains two nitrogen atoms and is substituted with two methyl groups at the 3 and 5 positions. The presence of these methyl groups influences the electron density and steric environment around the pyrazole ring, contributing to its unique reactivity and physical properties.

The synthesis of 3,5-Dimethylpyrazole is primarily achieved through the condensation reaction between acetylacetone and hydrazine. This reaction is typically carried out under controlled conditions, often in an aqueous alkaline medium. Acetylacetone, a beta-diketone, reacts with hydrazine hydrate to form the pyrazole ring structure, yielding 3,5-Dimethylpyrazole along with water as a byproduct. The efficiency and purity of the final product are dependent on the reaction parameters, such as temperature, pH, and stoichiometry. Advanced purification techniques, such as recrystallization from suitable solvents like cyclohexane or water, are employed to obtain high-purity 3,5-Dimethylpyrazole, essential for demanding applications like pharmaceuticals.

Key chemical properties of 3,5-Dimethylpyrazole include its moderate polarity and solubility in various organic solvents, such as methanol, ethanol, and acetone, as well as its slight solubility in water. It exhibits thermal stability, making it suitable for applications involving elevated temperatures. The compound's pKa value indicates it can act as a weak base, which is relevant in certain catalytic processes. Furthermore, the N-H group on the pyrazole ring allows it to participate in hydrogen bonding, acting as a hydrogen bond donor. This property is significant in its interactions within chemical systems and its role in blocking isocyanate groups.

Understanding these chemical properties is crucial for leveraging 3,5-Dimethylpyrazole in various fields. Its stability allows it to be used in applications requiring resistance to degradation, while its reactive N-H group and potential for coordination make it valuable in catalysis and as a ligand in organometallic chemistry.
