3 5-Bis(trifluoromethyl)pyrazole CAS 14704-41-7

1. Acts as a key intermediate for synthesizing agrochemicals, especially pyrazole-based herbicides and fungicides with high crop selectivity.
2. Serves 3 5-Bis(trifluoromethyl)pyrazole CAS 14704-41-7 as a fluorinated building block in pharmaceutical synthesis for developing drugs with enhanced metabolic stability and bioavailability.
3. Functions as a ligand precursor in coordination chemistry for preparing metal complexes with catalytic activity in organic transformations.

1. Store in sealed containers at 2-8℃ in a cool, dry, well-ventilated area away from ignition sources and strong oxidizers.
2. Keep 3 5-Bis(trifluoromethyl)pyrazole separated from strong acids and bases to prevent ring-opening reactions and decomposition of the trifluoromethyl groups.
3. Wear nitrile gloves, safety goggles, and a vapor respirator; handle in a fume hood to avoid skin contact and vapor inhalation.

1. The trifluoromethyl substituents improve the lipophilicity and chemical stability of downstream agrochemical and pharmaceutical products.
2. High 3 5-Bis(trifluoromethyl)pyrazole reactivity of the pyrazole ring enables selective functionalization for custom synthesis of target molecules.
3. Good solubility in organic solvents like dichloromethane and ethyl acetate simplifies reaction setup and product purification.

- GHS Classification: Flammable liquid (H226), skin irritant (H315), serious eye irritant (H319), respiratory irritant (H335), harmful if swallowed (H302).
- Vapor 3 5-Bis(trifluoromethyl)pyrazole may form explosive mixtures with air; skin contact can cause redness and itching; eye contact leads to severe irritation.
- Incompatible with strong oxidizers, concentrated acids, and alkalis, which may trigger exothermic reactions or release toxic fumes.
- UN Number: UN1224 (Flammable liquids, organic, n.o.s.), Packing Group III, subject to transport regulations for flammable organic liquids.
