1-(4-Fluorophenyl)-3,5-dimethyl-1H-pyrazole-4-carbaldehyde
1-(4-Fluorophenyl)-3,5-dimethyl-1H-pyrazole-4-carbaldehyde (CAS 890626-54-7; C12H11FN2O; molar mass 218.23 g/mol) is a fluorinated heterocyclic building block. It pairs a 3,5-dimethylpyrazole core, bearing a 4-fluorophenyl group on nitrogen, with a reactive aldehyde at the 4-position. The aldehyde makes it a versatile intermediate for condensation, reductive amination and multistep synthesis in pharmaceutical, agrochemical and fine-chemical research. Tech Serve Solutions supplies and exports it worldwide as a research-grade reagent.

Pharmaceutical intermediate
Used as a fluorinated pyrazole scaffold in medicinal-chemistry and drug-discovery programmes. The reactive aldehyde allows further elaboration toward more complex bioactive candidate molecules.
Heterocyclic synthesis building block
Serves as a starting material for constructing larger nitrogen heterocycles and fused-ring systems. The pre-formed, substituted pyrazole ring shortens multistep synthetic routes.
Aldehyde-based functional transformations
The 4-carbaldehyde group readily undergoes condensation (for example with amines to form imines/Schiff bases), reductive amination, Wittig and Knoevenagel reactions, and reduction or oxidation to the alcohol or carboxylic acid.
Fluorinated and agrochemical research
The 4-fluorophenyl substituent introduces fluorine into target structures, a common strategy in agrochemical and life-science discovery to modulate metabolic stability and binding.
Laboratory reagent and reference material
Supplied for use in synthetic and analytical laboratories as a defined organic intermediate for method development and small-scale preparative work.
