Trans-[(R)-cyano-(3-phenoxyphenyl)methyl] (1S,3S)-3-[(Z)-2-chloro-3,3,3-trifluoroprop-1-enyl]-2,2-dimethylcyclopropane-1-carboxylate

Trans-[(R)-cyano-(3-phenoxyphenyl)methyl] (1S,3S)-3-[(Z)-2-chloro-3,3,3-trifluoroprop-1-enyl]-2,2-dimethylcyclopropane-1-carboxylate is a synthetic pyrethroid insecticide with the molecular formula C23H19ClF3NO3 and CAS number 91465-08-6. This complex organic compound has a molecular weight of 449.8 g/mol and belongs to the class of neurotoxic insecticides that affect the nervous system of insects by disrupting sodium channel function.

This pyrethroid compound typically appears as a viscous liquid or solid at room temperature with low water solubility due to its hydrophobic nature. The presence of fluorine, chlorine, and aromatic rings in its structure contributes to its chemical stability and lipophilic properties. Its molecular structure contains multiple chiral centers, making stereochemistry important for biological activity and environmental fate.

This compound serves primarily as an active ingredient in professional insecticide formulations for agricultural and pest control applications. It is used in the synthesis of pyrethroid-based pesticides that target flying and crawling insects. The substance finds application in crop protection products and professional pest management solutions where high efficacy against resistant insect populations is required.

Safe handling requires appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and respiratory protection due to its Acute Tox. 2-4 classification. Work in well-ventilated areas or under fume extraction systems to prevent inhalation exposure. Avoid direct skin and eye contact, and ensure immediate access to emergency eyewash and safety shower facilities. Handle only in designated chemical handling areas with appropriate spill containment measures.

Proper storage requires a cool, dry, well-ventilated area away from heat sources, direct sunlight, and incompatible materials. Store in tightly sealed original containers with appropriate secondary containment to prevent environmental release. Due to its aquatic toxicity classification, ensure storage areas have adequate spill containment systems and are located away from water sources, drains, and environmentally sensitive areas.

Immediate first aid measures include removing contaminated clothing and rinsing affected skin with copious amounts of water for at least 15 minutes. In case of eye contact, flush immediately with water and seek medical attention. If inhaled, move the person to fresh air and monitor breathing. Given its high acute toxicity classification, seek immediate medical attention for any significant exposure and provide the safety data sheet to medical personnel.

Disposal must be conducted through licensed hazardous waste disposal facilities in accordance with local, national, and EU waste regulations. Due to its environmental hazard classification (Aquatic Acute 1, Aquatic Chronic 1), it requires special handling as hazardous waste. Empty containers should be triple-rinsed and disposed of according to local regulations. Never discharge into sewers, waterways, or the environment.

Transportation requires compliance with ADR Class 6.1 (toxic substances) regulations as Packing Group II material. Packages must bear appropriate hazard labels (GHS06, GHS09) and UN identification numbers. Transport vehicles require proper placarding and emergency response information. Only certified dangerous goods transport companies should handle shipments, ensuring proper documentation and emergency response procedures are in place.

This substance is subject to REACH regulation requiring registration for manufacture or import above one tonne per year. It falls under CLP regulation with mandatory hazard classification and labeling requirements (Danger signal word, GHS06/GHS09 pictograms). As a pesticide active ingredient, it may also be subject to biocide regulations and requires authorization for commercial use in pest control products within the EU.
