3,7-dimethyloctanenitrile

3,7-dimethyloctanenitrile is an organic nitrile compound with the molecular formula C10H19N and CAS number 40188-41-8. This branched aliphatic nitrile has a molecular weight of 153.26 g/mol and features two methyl substituents at positions 3 and 7 of an octane chain terminating in a nitrile group. It is classified as a skin irritant and sensitizer with moderate aquatic toxicity.

3,7-dimethyloctanenitrile is a liquid organic compound at room temperature with characteristic nitrile odor. As a branched aliphatic nitrile, it exhibits typical properties of this chemical class including limited water solubility due to its hydrophobic alkyl chain, while being soluble in organic solvents. The compound has a molecular weight of 153.26 g/mol and contains ten carbon atoms with two methyl branches.

3,7-dimethyloctanenitrile is primarily used as an intermediate in organic synthesis and chemical manufacturing processes. Its nitrile functional group makes it valuable for producing various derivatives including amines, carboxylic acids, and other nitrogen-containing compounds. The compound may also serve as a building block in pharmaceutical synthesis, specialty chemicals production, and as a precursor in the manufacture of polymers or agrochemicals.

3,7-dimethyloctanenitrile requires careful handling due to its skin irritant and sensitizing properties. Always wear appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and protective clothing. Work in well-ventilated areas or under fume extraction to avoid inhalation. Prevent skin and eye contact, and avoid generating aerosols. Use non-sparking tools and equipment, and ensure proper grounding of containers during transfer operations.

3,7-dimethyloctanenitrile should be stored in tightly sealed containers in a cool, dry, well-ventilated area away from heat sources and direct sunlight. Keep containers upright and protected from physical damage. Store away from incompatible materials such as strong oxidizing agents, acids, and bases. Maintain storage temperatures within recommended ranges and ensure adequate spill containment measures are in place in the storage area.

In case of skin contact with 3,7-dimethyloctanenitrile, immediately remove contaminated clothing and wash the affected area thoroughly with soap and water for at least 15 minutes. For eye contact, flush immediately with clean water for 15 minutes while holding eyelids open. If inhaled, move the person to fresh air and keep at rest. Seek medical attention if irritation persists or symptoms develop, especially given the compound's sensitizing properties.

3,7-dimethyloctanenitrile must be disposed of according to local and national hazardous waste regulations due to its classification as skin irritant and aquatic pollutant. Do not discharge into drains, waterways, or soil. Collect waste in appropriate containers for disposal through licensed waste management companies. Incineration at approved high-temperature facilities or chemical treatment may be suitable disposal methods depending on local regulations.

3,7-dimethyloctanenitrile is classified as ADR Class 9 (Miscellaneous dangerous goods), Packing Group III for transportation purposes. This classification requires appropriate packaging, marking, labeling, and documentation according to dangerous goods transport regulations. Use UN-approved packaging and ensure proper placarding of transport vehicles. Transport documents must include the correct shipping name, UN number, and hazard class information as required by ADR regulations.

3,7-dimethyloctanenitrile is subject to REACH regulation in Europe and must comply with CLP classification requirements as a skin irritant (Category 2), skin sensitizer (Category 1), and aquatic chronic toxicant (Category 2). The compound is not currently listed as a SVHC (Substance of Very High Concern). Users must follow proper classification, labeling, and safety data sheet requirements under these regulations.
