Butan-2-amine

Butan-2-amine is a secondary aliphatic amine with the molecular formula C4H11N and CAS number 13952-84-6. This organic compound has a molecular weight of 73.14 g/mol and belongs to the class of butylamine derivatives. It is characterized by an amino group attached to the second carbon of a butane chain, making it an isomer of other butylamine compounds. Due to its amine functional group, it exhibits basic properties and typical amine reactivity patterns in chemical processes.

Butan-2-amine is a flammable liquid at room temperature with characteristic amine odor properties. As a secondary amine with molecular formula C4H11N, it exhibits basic chemical behavior and can form salts with acids. The compound is likely miscible with polar solvents due to its amine functionality and moderate carbon chain length. Its flammable nature is reflected in its Flam. Liq. 2 classification, indicating relatively low flash point and significant fire hazard potential.

Butan-2-amine is primarily used as an intermediate in organic synthesis and pharmaceutical manufacturing. Its secondary amine structure makes it valuable for producing various chemical derivatives, including pharmaceuticals, agrochemicals, and specialty chemicals. The compound serves as a building block in the synthesis of more complex nitrogen-containing compounds and can be used in the production of surfactants, corrosion inhibitors, and rubber processing chemicals. Its reactivity with acids and other electrophiles makes it useful in various industrial chemical processes.

Butan-2-amine requires careful handling due to its corrosive (Skin Corr. 1A) and toxic properties (Acute Tox. 4). Essential personal protective equipment includes chemical-resistant gloves, safety goggles, and protective clothing to prevent skin and eye contact. Work should be conducted in well-ventilated areas or under fume hoods due to potential inhalation hazards. Avoid ignition sources as the compound is highly flammable (Flam. Liq. 2). Emergency eyewash and shower facilities must be readily accessible when working with this corrosive substance.

Butan-2-amine must be stored in a cool, dry, well-ventilated area away from heat sources, sparks, and open flames due to its Flam. Liq. 2 classification. Use appropriate chemical-resistant containers and ensure secondary containment to prevent spills. Store separately from acids, oxidizing agents, and incompatible materials to prevent dangerous reactions. The storage area should have appropriate fire suppression systems and be designed for flammable liquid storage. Keep containers tightly sealed to prevent vapor release and contamination.

Butan-2-amine contact requires immediate emergency response due to its Skin Corr. 1A classification. For skin contact, immediately flush the affected area with copious amounts of water for at least 15 minutes while removing contaminated clothing. In case of eye contact, rinse continuously with water and seek immediate medical attention. If inhaled, move the person to fresh air and provide respiratory support if needed. For ingestion, do not induce vomiting and seek immediate medical care. Always consult a physician after any exposure incident.

Butan-2-amine disposal must comply with local and European waste regulations due to its hazardous properties and Aquatic Acute 1 classification. The substance cannot be discharged into sewers or waterways due to its environmental toxicity. Disposal should be conducted through licensed hazardous waste contractors who can handle flammable and corrosive materials. Incineration at appropriate high-temperature facilities or chemical neutralization may be suitable methods. Always consult local environmental authorities and follow the safety data sheet recommendations for proper waste management procedures.

Butan-2-amine is classified as ADR Class 3 (flammable liquids), Packing Group II, requiring specific transport protocols for dangerous goods. Transportation must comply with European ADR regulations using appropriate UN-specification packaging designed for flammable and corrosive substances. Vehicles must carry proper placarding, emergency response information, and trained drivers with dangerous goods certification. The transport documentation must include all required hazard information and emergency contact details. Professional logistics companies experienced in chemical transport should handle shipment to ensure regulatory compliance.

Butan-2-amine is subject to multiple European chemical regulations including REACH registration requirements and CLP classification obligations. The substance is not currently listed as an SVHC (Substance of Very High Concern) under REACH. However, its hazardous properties require compliance with workplace safety regulations, environmental protection laws, and transport of dangerous goods legislation. Users must maintain safety data sheets, implement appropriate risk management measures, and ensure proper worker training. Industrial users may need to report usage under various national chemical inventory systems.
