Methyl substitution at the 1,5-positions can modulate the electronic effects and steric configuration of the pyrazole ring, helping improve lipophilicity and metabolic stability of derivatives. This provides advantages in active molecule structure optimization.
Pharmaceutical intermediates:
Used to construct biologically active pyrazole structures
Agrochemicals:
Used in the synthesis of fungicides, insecticides, and plant growth regulators
Fine chemicals:
Used as a functional heterocyclic raw material for R&D and process optimization
Research and fine chemicals:
Used for the synthesis of heterocyclic derivatives
