2-nitropropane

2-nitropropane is an organic nitro compound with the molecular formula C3H7NO2 and CAS number 79-46-9. This chemical substance has a molecular weight of 89.09 g/mol and belongs to the family of secondary nitroalkanes. It is classified as a flammable liquid with carcinogenic properties and acute toxicity. The compound is characterized by a nitro group (-NO2) attached to the central carbon atom of a propane chain, making it a versatile chemical intermediate used in various industrial applications.

2-nitropropane is a colorless to pale yellow liquid at room temperature with a characteristic sweet, fruity odor. It has a boiling point of approximately 120°C and a flash point around 24°C, which contributes to its flammable classification. The compound is moderately soluble in water and miscible with most organic solvents including alcohols and ethers. Its density is approximately 0.99 g/cm³, making it nearly as dense as water. These properties make it suitable for various solvent applications.

2-nitropropane serves primarily as a solvent for various industrial applications, particularly in the formulation of inks, paints, adhesives, and synthetic resins. It is used as a chemical intermediate in organic synthesis reactions and as a propellant component in some specialized applications. The compound also finds use in the production of pharmaceuticals and agrochemicals as a building block. Additionally, it serves as a laboratory reagent for analytical and research purposes, though its carcinogenic classification has limited some applications.

2-nitropropane requires strict safety protocols including wearing appropriate personal protective equipment such as chemical-resistant gloves, safety goggles, and respiratory protection when necessary. Work should be conducted in well-ventilated areas or under fume hoods to prevent inhalation exposure. Avoid contact with skin, eyes, and clothing, and eliminate all ignition sources due to its flammable nature. Given its carcinogenic classification (Carc. 1B), minimize exposure time and implement proper hygiene measures including thorough hand washing after handling.

2-nitropropane must be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames due to its flammable properties. Keep containers tightly sealed and store in original packaging or compatible containers made of suitable materials. The storage area should be equipped with appropriate fire suppression systems and spill containment measures. Keep away from incompatible materials such as strong oxidizers, bases, and reducing agents. Ensure storage areas comply with local fire codes and chemical storage regulations.

In case of skin contact with 2-nitropropane, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. If eye contact occurs, flush immediately with clean water for at least 15 minutes and seek medical attention. For inhalation exposure, move the person to fresh air and monitor breathing; provide artificial respiration if necessary. If ingested, do not induce vomiting and seek immediate medical attention. Always consult a physician and provide the safety data sheet.

2-nitropropane disposal must comply with local, national, and international hazardous waste regulations due to its toxic and carcinogenic properties. The substance should be collected in appropriate containers and disposed of through licensed hazardous waste disposal facilities. Incineration at high temperatures in specialized facilities equipped with appropriate emission controls is typically the preferred disposal method. Empty containers may require special treatment as they retain hazardous residues. Never dispose of this substance through regular waste streams or sewage systems.

2-nitropropane is classified under ADR Class 3 (Flammable Liquids), Packing Group III for transportation purposes. It must be transported in approved packaging that meets UN specification requirements and properly labeled with appropriate hazard labels and markings. Vehicles transporting this substance must comply with ADR regulations including proper placarding, driver training, and emergency equipment. Transport documents must accurately describe the substance and its hazards. Ensure compliance with route restrictions and tunnel categories as specified by local transportation authorities.

2-nitropropane is subject to comprehensive chemical regulations including REACH registration requirements in Europe and CLP classification for hazard communication. Due to its carcinogenic classification (Category 1B), it falls under strict occupational exposure limits and may be subject to authorization procedures. The substance must be handled according to chemical safety regulations and workplace safety directives. Users must maintain safety data sheets, implement risk management measures, and comply with notification requirements. Regular monitoring and health surveillance may be mandatory in occupational settings.
