2,4-dichloro-3-ethyl-6-nitrophenol

2,4-dichloro-3-ethyl-6-nitrophenol is a chlorinated nitrophenol compound with the molecular formula C8H7Cl2NO3 and CAS number 99817-36-4. This organic chemical features a phenol ring substituted with two chlorine atoms, one ethyl group, and one nitro group. With a molecular weight of 236.05 g/mol, it belongs to the family of halogenated aromatic compounds and exhibits significant hazard properties including acute toxicity and environmental persistence.

2,4-dichloro-3-ethyl-6-nitrophenol is a solid organic compound at room temperature due to its substituted phenolic structure. The presence of chlorine atoms and the nitro group typically imparts a yellowish color to such compounds. Its solubility characteristics are influenced by the polar nitro and hydroxyl groups versus the lipophilic chlorine substituents and ethyl group, resulting in moderate solubility in organic solvents and limited water solubility.

2,4-dichloro-3-ethyl-6-nitrophenol is primarily used as an intermediate in organic synthesis and pharmaceutical manufacturing. Its multiple functional groups make it valuable for chemical transformations in the production of specialized compounds. The compound may serve as a precursor in the synthesis of agrochemicals, dyes, or other fine chemicals where selective substitution patterns are required for biological activity or specific chemical properties.

2,4-dichloro-3-ethyl-6-nitrophenol requires careful handling due to its Acute Tox. 3, Eye Dam. 1, and Skin Sens. 1 classifications. Essential PPE includes chemical-resistant gloves, safety goggles, and protective clothing to prevent skin and eye contact. Work in well-ventilated areas or under fume extraction to avoid inhalation. Avoid generating dust and ensure emergency eyewash stations are accessible. Personnel should be trained on proper handling procedures and emergency response protocols.

2,4-dichloro-3-ethyl-6-nitrophenol should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Keep containers away from oxidizing agents and strong bases that could react with the phenolic group. Storage areas must be equipped with appropriate containment systems and maintained at stable temperatures to prevent degradation. Access should be restricted to trained personnel only, with proper inventory management and safety signage.

Immediate action is required due to the substance's Eye Dam. 1 and Skin Sens. 1 properties. For eye contact, flush immediately with copious amounts of water for at least 15 minutes and seek immediate medical attention. For skin contact, remove contaminated clothing and wash affected area thoroughly with soap and water. If inhaled, move to fresh air immediately. In case of ingestion, do not induce vomiting and seek immediate medical care. Always consult the safety data sheet for specific first aid measures.

2,4-dichloro-3-ethyl-6-nitrophenol must be disposed of as hazardous waste through licensed waste management companies due to its toxic and environmentally hazardous properties (Aquatic Acute 1, Aquatic Chronic 1). The compound cannot be disposed of via normal waste streams or sewage systems. Disposal methods typically include high-temperature incineration at approved facilities. All disposal activities must comply with local, national, and EU waste regulations, requiring proper documentation and tracking throughout the disposal process.

2,4-dichloro-3-ethyl-6-nitrophenol is classified under ADR Class 6.1 (toxic substances), Packing Group III for transport purposes. Shipments must use appropriate UN-specification packaging and display proper hazard labels including the GHS06 (skull and crossbones) pictogram. Transport documentation must include proper shipping names, hazard classes, and emergency response information. Only certified carriers experienced in handling toxic chemicals should transport this substance, following all ADR/RID regulations for dangerous goods.

2,4-dichloro-3-ethyl-6-nitrophenol is subject to REACH registration requirements for import and use within the EU, though it is not currently listed as a SVHC (Substance of Very High Concern). The substance must comply with CLP regulation for classification and labeling as indicated by its hazard classes and GHS pictograms. Users must maintain safety data sheets, implement appropriate risk management measures, and may face restrictions depending on intended use and local environmental regulations.
