Applications of 145091-87-8
| Industry | Application | Process |
|---|---|---|
| Pesticides | Intermediate for novel insecticides and acaricides | Used in synthesizing high-efficacy, low-toxicity pyrazole-based pesticides—such as fluxapyroxad derivatives—via substitution or condensation reactions with haloalkanes, carboxylic acid derivatives, and other reagents to construct the active molecular scaffold |
| Pharmaceuticals | Intermediate for anti-inflammatory and antitumor drug candidates | Employed in constructing heterocyclic drug molecules—for example, serving as a key pyrazole ring precursor—and functionalized via O-alkylation, N-acylation, and other modifications to introduce targeted pharmacophores |
| Materials | Monomer for high-performance polymers and intermediate for functional dyes | Utilized in condensation or coupling reactions involving its hydroxyl group and the nitrogen atom on the pyrazole ring to produce heat-resistant pyrazole-based polyamides, fluorescent labeling reagents, or metal–organic framework (MOF) ligands |
