Description
Pr

1-Methyl-3-(trifluoromethyl)-1H-pyrazol-5-ol (CAS 122431-37-2) is a fluorinated heterocyclic chemical used primarily as a key intermediate in the synthesis of agrochemicals, most notably the herbicide pyroxasulfone. [ 1, 2, 3]

Chemical Profile & Properties

Molecular Formula: $\text{C}_5\text{H}_5\text{F}_3\text{N}_2\text{O}$

Molecular Weight: 166.10 g/mol

Melting Point: 177°C – 179°C

Appearance: Colorless or white crystalline solid

Solubility: Soluble in polar aprotic solvents like DMSO and DMF

Role in Agricultural Chemistry

Pyroxasulfone Synthesis: This compound acts as a foundational building block for manufacturing pyroxasulfone, a broad-spectrum residual herbicide used for weed control in crops like corn, soybeans, and wheat.

Regioselectivity: The N1-methylation on the pyrazole ring blocks competing N-alkylation side reactions, allowing for clean, high-yield O-difluoromethylation steps during manufacturing.

Purity Requirements: Commercial-grade synthesis typically requires a purity level of $>98\%$ to ensure proper downstream biological activity of the final agrochemical product.
