This chemical substance has a molecular weight of 303.3 g/mol and contains phosphorus, sulfur, and nitrogen functional groups. It is classified as a hazardous substance with multiple toxicity concerns including acute toxicity, specific target organ toxicity, and environmental hazards. The compound requires careful handling due to its dangerous properties.

4-[ethoxy(phenyl)phosphinothioyl]oxybenzonitrile has a molecular weight of 303.3 g/mol and molecular formula C15H14NO2PS. As an organophosphorus compound containing aromatic rings, it likely exists as a solid at room temperature. The presence of both polar (nitrile, phosphinothioyl) and nonpolar (ethoxy, phenyl) groups suggests moderate solubility in organic solvents. Specific physical properties such as melting point, boiling point, and exact appearance would require detailed technical specifications from the manufacturer.

4-[ethoxy(phenyl)phosphinothioyl]oxybenzonitrile is primarily used as a chemical intermediate in pharmaceutical and agrochemical synthesis. Its organophosphorus structure makes it valuable for developing compounds with biological activity. The substance may serve as a building block for more complex molecules in research and development applications. Due to its hazardous classification, its use is restricted to professional and industrial settings where appropriate safety measures and expertise are available.

4-[ethoxy(phenyl)phosphinothioyl]oxybenzonitrile requires strict safety precautions due to its Acute Tox. 3 and 4 classifications and STOT SE 1 rating. Personal protective equipment must include chemical-resistant gloves, safety goggles, and respiratory protection. Work should be conducted in well-ventilated areas or under fume hoods. Avoid skin and eye contact, and prevent inhalation. Emergency procedures and safety data sheets must be readily available. Only trained personnel should handle this substance.

4-[ethoxy(phenyl)phosphinothioyl]oxybenzonitrile must be stored in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Containers should be tightly sealed and properly labeled with hazard information. Storage areas must be secure and accessible only to authorized personnel. Given its toxicity classification, segregation from food, feed, and other consumables is essential. Regular inspection of containers for damage or leaks is recommended to prevent accidental exposure.

Immediate action is required upon contact with 4-[ethoxy(phenyl)phosphinothioyl]oxybenzonitrile due to its acute toxicity. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water. In case of eye contact, flush immediately with clean water for at least 15 minutes. If inhaled, move to fresh air immediately. For ingestion, do not induce vomiting. Seek immediate medical attention in all cases and provide the safety data sheet to medical personnel.

4-[ethoxy(phenyl)phosphinothioyl]oxybenzonitrile must be disposed of as hazardous waste through licensed waste management companies in accordance with local and European regulations. The substance cannot be disposed of in regular waste streams due to its toxicity and environmental hazard classification (Aquatic Chronic 2). Containers must be properly labeled and transported according to ADR Class 6.1 requirements. Incineration at authorized high-temperature facilities is typically the preferred disposal method for organophosphorus compounds.

4-[ethoxy(phenyl)phosphinothioyl]oxybenzonitrile is classified under ADR Class 6.1 (Toxic substances) Packing Group II, indicating significant toxicity requiring special transport precautions. Packaging must meet UN specifications for toxic substances and be properly marked with hazard labels including GHS06, GHS08, and GHS09 pictograms. Transport documentation must include proper shipping names, hazard classes, and emergency response information. Only certified carriers familiar with dangerous goods regulations should handle transportation.

4-[ethoxy(phenyl)phosphinothioyl]oxybenzonitrile is subject to multiple European regulations including REACH registration requirements and CLP classification standards. The substance is not currently listed as an SVHC (Substance of Very High Concern) but must comply with worker protection and environmental safety regulations. Its classification under multiple hazard categories (Acute Tox., STOT SE 1, Eye Irrit. 2, Aquatic Chronic 2) triggers specific labeling, safety data sheet, and handling requirements under CLP regulation.
