1-[1-ethyl-4-[3-(2-methoxyethoxy)-2-methyl-4-methylsulfonylbenzoyl]pyrazol-5-yl]oxyethyl methyl carbonate

1-[1-ethyl-4-[3-(2-methoxyethoxy)-2-methyl-4-methylsulfonylbenzoyl]pyrazol-5-yl]oxyethyl methyl carbonate is a complex organic chemical compound with the molecular formula C21H28N2O9S and CAS number 1101132-67-5. This substance has a molecular weight of 484.5 g/mol and belongs to the carbonate ester family. It contains pyrazole and benzoyl functional groups with methoxyethoxy and methylsulfonyl substituents, making it a highly specialized chemical intermediate.

This compound is a complex organic molecule with a molecular weight of 484.5 g/mol and molecular formula C21H28N2O9S. The presence of multiple functional groups including carbonate ester, pyrazole ring, and sulfonyl groups suggests it likely exists as a solid at room temperature. The methoxyethoxy substituent indicates potential solubility in polar organic solvents. Specific physical properties such as melting point, boiling point, and exact solubility data require detailed analytical characterization.

This compound is primarily used as a specialized chemical intermediate in pharmaceutical and agrochemical synthesis. Its complex structure containing pyrazole and benzoyl moieties makes it valuable for developing bioactive compounds. The carbonate ester functionality can serve as a protecting group or reactive site in multi-step organic synthesis. Given its molecular complexity, it is typically employed in research and development applications rather than large-scale industrial processes.

Safe handling requires appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing due to its Carc. 2 and Repr. 2 classifications. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid direct skin and eye contact, and prevent ingestion. Use proper grounding procedures to prevent static discharge. Emergency eyewash stations and safety showers should be readily accessible when working with this material.

Store this compound in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Given its hazard profile (Carc. 2, Repr. 2, STOT RE 2), it should be stored in designated areas with restricted access and appropriate warning labels. Keep containers upright and protected from physical damage. Segregate from strong oxidizing agents and bases. Regular inventory checks and proper labeling are essential for safe storage management.

Immediate action is required due to the substance's hazardous properties. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water for at least 15 minutes. In case of eye contact, flush immediately with clean water for at least 15 minutes while holding eyelids open. If inhaled, move person to fresh air and seek medical attention. For ingestion, do not induce vomiting and seek immediate medical attention. Always consult the safety data sheet for specific first aid measures.

Disposal must comply with local, national, and international environmental regulations due to its Aquatic Acute 1 and Aquatic Chronic 1 classifications. This substance cannot be disposed of in regular waste streams or sewage systems. Contact licensed hazardous waste disposal companies for proper treatment and disposal. Small quantities may require incineration at authorized high-temperature facilities. Maintain detailed disposal records and ensure proper waste classification documentation according to applicable waste codes.

Transportation follows ADR Class 9 (Miscellaneous dangerous goods), Packing Group III regulations. This classification requires appropriate hazard labels, proper packaging specifications, and transport documentation. Vehicles must carry appropriate emergency response information and drivers need proper training for dangerous goods transport. Packages must be marked with the correct shipping name, UN number, and hazard labels. Ensure compliance with international transport regulations (ADR/RID for road/rail, IMDG for sea, IATA for air transport).

This substance is subject to multiple regulatory frameworks including REACH registration requirements in Europe and CLP classification obligations. Its Carc. 2 and Repr. 2 classifications trigger specific labeling, packaging, and notification requirements. While not currently listed as an SVHC, its hazardous properties require compliance with occupational exposure limits and workplace safety regulations. Users must maintain safety data sheets, implement risk management measures, and ensure proper worker training according to chemical safety legislation.
