2,4-dichloro-3-ethylphenol

2,4-dichloro-3-ethylphenol is an organochlorine compound with the molecular formula C8H8Cl2O and CAS number 121518-45-4. This phenolic derivative features two chlorine atoms at positions 2 and 4, and an ethyl group at position 3 on the benzene ring. With a molecular weight of 191.05 g/mol, it is classified as a hazardous substance requiring careful handling due to its corrosive and aquatic toxicity properties.

2,4-dichloro-3-ethylphenol is a chlorinated phenolic compound with a molecular weight of 191.05 g/mol and formula C8H8Cl2O. As a substituted phenol, it typically appears as a crystalline solid at room temperature. The presence of chlorine substituents and the ethyl group affects its solubility profile, making it moderately soluble in organic solvents but less soluble in water compared to unsubstituted phenol.

2,4-dichloro-3-ethylphenol is primarily used as an intermediate in chemical synthesis and pharmaceutical manufacturing. Its chlorinated phenolic structure makes it valuable for producing specialized organic compounds, including potential antimicrobial agents and other bioactive molecules. It may also serve as a building block in the synthesis of agrochemicals, dyes, or other specialty chemicals requiring specific substitution patterns on the phenolic ring.

2,4-dichloro-3-ethylphenol must be handled with extreme caution due to its Skin Corr. 1B classification. Always wear appropriate PPE including chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or under fume hoods to avoid inhalation. Never allow direct skin or eye contact. Use appropriate tools for handling and ensure emergency shower and eyewash stations are readily accessible in the work area.

2,4-dichloro-3-ethylphenol should be stored in tightly sealed, corrosion-resistant containers in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Keep containers upright and properly labeled according to GHS requirements. Store separately from strong bases, oxidizing agents, and reactive metals. Ensure storage areas have appropriate containment measures and are accessible only to trained personnel with proper safety equipment.

Skin contact with 2,4-dichloro-3-ethylphenol requires immediate action due to its corrosive nature. Remove contaminated clothing and flush affected skin with copious amounts of water for at least 20 minutes. For eye contact, rinse immediately with water for 15 minutes while holding eyelids open. If inhaled, move to fresh air immediately. Seek immediate medical attention for all exposure routes and provide the safety data sheet to medical personnel.

2,4-dichloro-3-ethylphenol must be disposed of as hazardous waste through licensed waste management companies in accordance with local and EU regulations. Due to its aquatic toxicity classification, it cannot be discharged into waterways or sewage systems. Contact certified hazardous waste disposal services for proper collection and treatment. Maintain disposal records as required by environmental regulations and ensure containers are properly labeled before disposal.

2,4-dichloro-3-ethylphenol is classified as ADR Class 8 (corrosive substances), Packing Group II, requiring specialized transport procedures. Use appropriate UN-specification packaging designed for corrosive materials. Vehicles must carry proper ADR documentation, emergency response information, and appropriate safety equipment. Only trained drivers with ADR certification for Class 8 materials should transport this substance. Ensure proper labeling and placarding according to ADR requirements.

2,4-dichloro-3-ethylphenol is subject to EU REACH regulation requiring registration for manufacture or import above specified tonnages. Under CLP regulation, it must be classified and labeled with GHS05 and GHS09 pictograms and 'Danger' signal word. While not currently listed as SVHC, its aquatic toxicity may subject it to environmental discharge restrictions. Companies must maintain safety data sheets and ensure proper worker training and exposure controls.
