Benzidine

Benzidine is an organic compound historically used in manufacturing dyes, especially for coloring textiles, paper, and leather. Chemically, it consists of two benzene rings connected by an amino group. However, benzidine is highly toxic and has been linked to serious health risks, including cancer, particularly of the bladder. Due to these dangers, its use has been largely phased out or banned in many countries. Proper handling and safety measures are essential when working with benzidine since exposure can occur through inhalation or skin contact, posing significant health hazards.
