2-tert-butyl-4,6-dinitrophenol

2-tert-butyl-4,6-dinitrophenol is an organic chemical compound with the molecular formula C10H12N2O5 and CAS number 1420-07-1. This nitrophenol derivative contains a tert-butyl group and two nitro groups attached to a phenol ring, giving it a molecular weight of 240.21 g/mol. It is classified as a highly hazardous substance with reproductive toxicity, acute toxicity, and environmental dangers, requiring careful handling in industrial applications.

2-tert-butyl-4,6-dinitrophenol is typically a crystalline solid at room temperature with a characteristic yellow to orange color. The compound has limited water solubility due to its organic structure but dissolves well in organic solvents. Its nitro groups make it chemically reactive and potentially unstable under certain conditions. The molecular structure with both electron-withdrawing nitro groups and the bulky tert-butyl substituent influences its physical and chemical behavior.

2-tert-butyl-4,6-dinitrophenol is primarily used as a chemical intermediate in the synthesis of other organic compounds and as a research chemical in laboratory applications. It may serve as a precursor in the production of dyes, pharmaceuticals, or agrochemicals. Due to its high toxicity profile and environmental hazards, its applications are typically limited to specialized industrial processes where proper safety measures and waste management systems are in place.

2-tert-butyl-4,6-dinitrophenol requires strict safety protocols including full personal protective equipment: chemical-resistant gloves, safety goggles, respiratory protection, and protective clothing. Work must be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid skin contact and ingestion completely due to its acute toxicity classification. Only trained personnel should handle this substance, and emergency procedures must be readily available given its dangerous classification under GHS pictograms GHS08, GHS06, and GHS09.

2-tert-butyl-4,6-dinitrophenol must be stored in a cool, dry, well-ventilated area away from heat sources, direct sunlight, and incompatible materials. Keep containers tightly sealed and use appropriate secondary containment to prevent environmental release. Store separately from oxidizing agents, reducing agents, and bases due to potential chemical incompatibilities. The storage area should be secure, clearly labeled, and accessible only to authorized personnel familiar with the substance's hazardous properties and emergency procedures.

Immediate medical attention is required for any exposure to 2-tert-butyl-4,6-dinitrophenol due to its acute toxicity. For skin contact, remove contaminated clothing and rinse affected area with copious amounts of water for at least 15 minutes. If inhaled, move to fresh air immediately and monitor breathing. In case of eye contact, flush with water for 15 minutes while holding eyelids open. Never induce vomiting if ingested. Contact poison control and seek emergency medical care immediately for any exposure route.

2-tert-butyl-4,6-dinitrophenol must be disposed of as hazardous waste through licensed waste management companies specialized in toxic chemical disposal. Never discharge into sewers, water bodies, or regular waste streams due to its environmental toxicity classification (Aquatic Acute 1, Aquatic Chronic 1). Incineration at high temperatures in appropriate facilities is typically required. All disposal activities must comply with local, national, and EU waste regulations, and proper waste classification codes must be assigned for tracking and documentation purposes.

2-tert-butyl-4,6-dinitrophenol is classified under ADR as Class 6.1 (toxic substances), Packing Group II, indicating significant transport hazards. Shipments require appropriate UN-specification packaging, proper labeling with toxic substance markings, and transport documentation including safety data sheets. Vehicles must carry emergency equipment and drivers need hazardous materials certification. Transport must comply with ADR regulations for toxic substances, including route restrictions, quantity limitations, and emergency response procedures during transit.

2-tert-butyl-4,6-dinitrophenol is subject to comprehensive chemical regulations including REACH registration requirements in the EU and CLP classification as a Category 1B reproductive toxicant. While not currently listed as an SVHC, its reproductive toxicity classification subjects it to authorization and restriction considerations. Users must comply with occupational exposure limits, environmental discharge restrictions, and worker health surveillance requirements. Import/export may require permits, and industrial users need risk assessments and appropriate risk management measures.
