3,5-Dimethylpyrazole is an organic compound belonging to the pyrazole family. Pyrazoles are a class of simple aromatic heterocycles characterized by a 5-membered ring with two adjacent nitrogen atoms (N-N).

The "3,5-Dimethyl" part of the name indicates that this specific pyrazole has two methyl groups (–CH₃) attached to the carbon atoms at the 3 and 5 positions of the ring.

Chemical Formula: C₅H₈N₂
Molar Mass: 96.13 g/mol
CAS Number: 67-51-6
Appearance: It typically appears as white to off-white crystalline flakes or powder.
Melting Point: ~106-108 °C
Solubility: Moderately soluble in water and highly soluble in common organic solvents like ethanol, acetone, and dichloromethane.

Key Properties and Significance

The primary importance of 3,5-Dimethylpyrazole lies in its chemical behavior, specifically its ability to act as a ligand in coordination chemistry.
1. Ligand in Coordination Chemistry:
A ligand is a molecule or ion that binds to a central metal atom to form a complex. 3,5-Dimethylpyrazole is an excellent N-donor ligand.
Coordination Site: It donates the electron pair from its pyrrolic nitrogen (the NH nitrogen) to metal ions. The adjacent "pyridinic" nitrogen (the one with a lone pair) can also participate in bonding, often through hydrogen bonding or weaker interactions, making it a versatile building block.
Bulky Group: The two methyl groups make the ligand relatively bulky or "sterically hindered." This bulkiness helps control how the ligands arrange themselves around a metal center, preventing the formation of overcrowded complexes and leading to specific, often more stable, molecular geometries.
Ability to Form Hydrogen Bonds: The N-H group on the ring is a good hydrogen bond donor, which is crucial for forming extended network structures (like Metal-Organic Frameworks or MOFs) or for stabilizing crystal structures.
2. Prototypical Example of a Self-Assembling System:
3,5-Dimethylpyrazole is famously known for forming a hydrogen-bonded dimer. The N-H group of one molecule forms a strong hydrogen bond with the nitrogen atom of a second molecule, creating a stable, cyclic dimer. This property is a classic example in textbooks of how molecules can self-associate.
3. Precursor to Other Compounds:
It can be used as a starting material (building block) for the synthesis of more complex molecules, including pharmaceuticals and agrochemicals, though its primary use is in research chemistry.
Primary Applications and Uses
Synthesis of Metal Complexes: Its main application is in academic and industrial research to create novel coordination complexes with a wide range of metals (e.g., Zinc, Copper, Cobalt, Silver, Lanthanides). These complexes are studied for their:
Magnetic properties
Catalytic activity (as catalysts for organic reactions)
Structural diversity
Potential biological activity (e.g., antimicrobial, anticancer)
Building Block for Metal-Organic Frameworks (MOFs): Researchers use it as a linker or a co-ligand to construct MOFs—porous materials with applications in gas storage (e.g., H₂, CO₂), separation, and drug delivery. Its hydrogen-bonding capability is particularly useful here.
Agrochemical Research: While not a final product itself, pyrazole derivatives are a very important class of compounds in the development of fungicides and herbicides. 3,5-Dimethylpyrazole serves as a core structure for synthesizing and testing new active ingredients.
Corrosion Inhibition: Some pyrazole derivatives, including those based on this structure, are investigated for their ability to inhibit the corrosion of metals, particularly in acidic environments.
Safety and Handling
GHS Hazard Statements: It is generally classified as an irritant.
H315: Causes skin irritation.
H319: Causes serious eye irritation.
H335: May cause respiratory irritation.
Precautionary Statements: It should be handled with standard laboratory precautions: wearing gloves, safety glasses, and working in a well-ventilated area or fume hood. Avoid breathing its dust.
Summary
In short, 3,5-Dimethylpyrazole is a specialty organic compound most valued in chemical research for its role as a versatile ligand. Its key features are its two nitrogen atoms that can bind to metals and its two methyl groups that provide steric bulk. It is a fundamental tool for synthesizing and studying metal complexes, MOFs, and other functional materials.
