1-(4,6-dimethoxypyrimidin-2-yl)-3-(2-ethylsulfonylimidazo[1,2-a]pyridin-3-yl)sulfonylurea

1-(4,6-dimethoxypyrimidin-2-yl)-3-(2-ethylsulfonylimidazo[1,2-a]pyridin-3-yl)sulfonylurea is a complex organic compound with the molecular formula C16H18N6O7S2 and CAS number 141776-32-1. This sulfonylurea derivative has a molecular weight of 470.5 g/mol and contains multiple heterocyclic ring systems including pyrimidine and imidazo[1,2-a]pyridine moieties. The compound is classified as hazardous to aquatic environments and requires careful handling according to GHS regulations.

The compound exhibits a molecular weight of 470.5 g/mol with the molecular formula C16H18N6O7S2. As a sulfonylurea derivative containing multiple polar functional groups including methoxy, sulfonyl, and urea moieties, it likely demonstrates moderate to good solubility in polar solvents. The presence of aromatic ring systems suggests stability under normal conditions. Specific physical properties such as melting point, density, and exact solubility parameters should be determined through analytical testing.

This sulfonylurea compound is primarily utilized in agricultural applications as an active ingredient in herbicide formulations. The unique molecular structure combining pyrimidine and imidazopyridine rings provides selective herbicidal activity against specific weed species. It is commonly incorporated into crop protection products for professional agricultural use. The compound may also serve as an intermediate in the synthesis of other agrochemical products or as a reference standard in analytical laboratories.

Safe handling requires standard personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing to prevent skin and eye contact. Work in well-ventilated areas or use local exhaust ventilation to minimize inhalation exposure. Avoid generating dust and prevent environmental release due to its aquatic toxicity classification. Wash hands thoroughly after handling and before eating or drinking. Follow good industrial hygiene practices and consult the safety data sheet for specific handling requirements.

Store the compound in a cool, dry place away from direct sunlight and heat sources in tightly sealed original containers. Maintain storage temperatures according to manufacturer specifications and protect from moisture to prevent degradation. Keep away from incompatible materials such as strong oxidizing agents and bases. Ensure storage areas have adequate ventilation and secondary containment to prevent environmental contamination. Implement appropriate inventory management and restrict access to authorized personnel only.

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, rinse immediately with clean water for 15-20 minutes and remove contact lenses if present. If inhaled, move the person to fresh air and keep at rest. In case of ingestion, rinse mouth with water but do not induce vomiting. Seek immediate medical attention for all exposure routes and provide the safety data sheet to medical personnel.

Disposal must comply with local, national, and EU waste regulations due to its aquatic toxicity classification. The compound requires treatment as hazardous waste and should be disposed of through licensed waste management facilities capable of handling chemical waste. Never discharge to drains, waterways, or soil. Small quantities may be suitable for high-temperature incineration with appropriate emission controls. Consult local environmental authorities and waste contractors for specific disposal requirements and approved treatment methods.

The compound is classified as ADR Class 9 (Miscellaneous dangerous substances) Packing Group III, indicating moderate transport hazard requiring specific packaging and documentation. Use UN-approved packaging suitable for Packing Group III materials and ensure proper labeling with Class 9 hazard labels. Transport documents must include proper shipping name, UN number, and emergency response information. Drivers require ADR training and vehicles must carry appropriate safety equipment. Prevent package damage and environmental release during transport.

The compound is subject to EU REACH regulation requiring registration, evaluation, and authorization for commercial use. It falls under CLP regulation for classification, labeling, and packaging as indicated by its GHS09 pictogram and Warning signal word. While not currently identified as a Substance of Very High Concern (SVHC), its aquatic toxicity classification requires compliance with environmental protection regulations. Biocidal or plant protection product regulations may apply depending on intended use, requiring specific authorizations for market access.
