The compound is employed in crop protection formulations for controlling broadleaf weeds and grasses in various agricultural settings. Its specific molecular structure provides selectivity and efficacy against target weed species while showing tolerance in certain crops.

Safe handling requires wearing appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or use local exhaust ventilation to minimize exposure. Avoid direct contact with skin, eyes, and inhalation of dust or vapors. The compound carries a Warning signal word and requires careful handling due to its environmental hazard classification. Always wash hands thoroughly after handling and avoid eating, drinking, or smoking during use.

Store this compound in a cool, dry, well-ventilated area away from direct sunlight and heat sources. Keep containers tightly closed and properly labeled in their original packaging. Due to its Aquatic Acute 1 and Aquatic Chronic 1 classifications, ensure storage areas have appropriate containment measures to prevent environmental release. Store away from incompatible materials and ensure compliance with local chemical storage regulations. Maintain storage temperatures as recommended by the manufacturer to preserve stability.

In case of skin contact, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15-20 minutes and remove contact lenses if present. If inhaled, move the person to fresh air and keep them at rest. If swallowed, do not induce vomiting and rinse mouth with water. Seek immediate medical attention in all cases and provide the safety data sheet to medical personnel.

Disposal must comply with local, national, and international environmental regulations due to its Aquatic Acute 1 and Aquatic Chronic 1 classifications. Never dispose of this compound in sewers, waterways, or regular waste streams. Contact licensed waste disposal companies specialized in hazardous chemical waste management. Small quantities may require incineration at authorized high-temperature facilities. Always consult the safety data sheet and local environmental authorities for specific disposal requirements and approved disposal sites.
