The chemical formula of xylidines is C8H11N, or (CH3)2C6H3NH2. They are stable and combustible and react with strong oxidizing agents. They may be light sensitive. The CAS number for the isomer mixture is
Xylidines are also used as a component of the Tonka rocket fuel.

People can be exposed to xylidines in the workplace by breathing them in, skin absorption, swallowing them, and eye contact. The Occupational Safety and Health Administration (OSHA) has set the legal limit (Permissible exposure limit) for xylidine exposure in the workplace as 5 ppm (25 mg/m3) skin exposure over an 8-hour workday. The National Institute for Occupational Safety and Health (NIOSH) has set a Recommended exposure limit (REL) of 2 ppm (10 mg/m3) skin exposure over an 8-hour workday. At levels of 50 ppm, xylidine is immediately dangerous to life and health.
