Overview

Dimethylaniline (DMA) is an organic chemical compound, a substituted derivative of aniline. It is a tertiary amine featuring a dimethylamino group attached to a phenyl group. This oily liquid is colorless when pure, but commercial samples are often yellow. It is an important precursor to dyes such as crystal violet.

Uses

Dimethylaniline is a key precursor to commercially important triarylmethane dyes such as malachite green and crystal violet. It serves as a promoter in the curing of polyester and vinyl ester resins. Additionally, DMA is used as a precursor to other organic compounds.

Regulatory

Dimethylaniline is regulated under various international guidelines to ensure safe handling and usage. The permissible exposure limit (PEL) set by NIOSH is TWA 5 ppm (25 mg/m³) [skin]. The recommended exposure limit (REL) is TWA 5 ppm (25 mg/m³) ST 10 ppm (50 mg/m³) [skin]. The immediate danger to life or health (IDLH) concentration is 100 ppm.

Monitoring

Monitoring of Dimethylaniline in environmental and occupational settings is crucial to ensure compliance with regulatory limits. Analytical methods such as gas chromatography (GC) and liquid chromatography (LC) are commonly used for this purpose.

Health Impact

Dimethylaniline exposure can lead to various health effects. The median lethal dose (LD₅₀) for rats is 1410 mg/kg (oral). The lowest published lethal concentration (LC_Lo) for rats is 50 ppm (4 hr). Chronic exposure may result in methemoglobinemia, a condition where hemoglobin is unable to carry oxygen efficiently.

Environmental Impact

Dimethylaniline can have significant environmental impacts if not managed properly. It is slightly soluble in water and can contaminate water bodies, affecting aquatic life. Proper disposal and treatment of waste containing DMA are essential to minimize environmental risks.

Safety Measure

Handling Dimethylaniline requires stringent safety measures. Personal protective equipment (PPE) such as gloves, goggles, and lab coats should be worn. Adequate ventilation and fume hoods are necessary to prevent inhalation exposure. In case of spills, use appropriate absorbent materials and dispose of them according to local regulations.
