The invention relates to a process for manufacturing of 3-halomethyl-substituted 1- methyl-1H-pyrazole-4-carbonitrile compounds, including 3-halomethyl-substituted 5- hydroxy-1-methyl-1H-pyrazole-4-carbonitrile compounds which may be isolated and/or purified or in-situ generated, and of derivatives thereof. The invention also relates to a process for manufacturing of intermediates for the manufacturing of the 3-halomethyl- substituted 1-methyl-1H-pyrazole-4-carbonitrile compounds, including 3-halomethyl- substituted 5-hydroxy-1-methyl-1H-pyrazole-4-carbonitrile compound. Further the inven- tion relates to some new derivatives of the 3-halomethyl-substituted 1-methyl-1H- pyrazole-4-carbonitrile compounds, including of the 3-halomethyl-substituted 5-hydroxy-1- methyl-1H-pyrazole-4-carbonitrile compounds. Further the invention relates to some new derivatives of the 3-halomethyl-substituted 1-methyl-1H-pyrazole-4-carbonitrile com- pounds, including of the 3-halomethyl-substituted 5-hydroxy-1-methyl-1H-pyrazole-4- carbonitrile compounds, e.g., the compound 5-chloro-3-difluoromethyl-1-methyl-1H- pyrazole-4-carbonitrile (Cl-DFPACN), and the compound 5-fluoro-3-difluoromethyl-1- methyl-1H-pyrazole-4-carbonitrile (F-DFPACN).
