The synthetic compound o,p′-DDE serves as a model substance in laboratory experiments, enabling the exploration of organochlorine impacts on biological systems. As an organochlorine compound, it combines chlorine and carbon atoms and plays a vital role in various products, including insecticides, herbicides, and flame retardants. Numerous studies have extensively examined o,p′-DDE′s effects on diverse biological systems. Researchers utilize o,p′-DDE in laboratory applications to investigate its influence on the endocrine, reproductive, and immune systems. Moreover, its role in cancer and disease development is also a subject of inquiry. o,p′-DDE′s impact on the environment, particularly aquatic, terrestrial, and soil organisms, has been a key focus. Acting as an endocrine disruptor, o,p′-DDE binds to the androgen receptor, hampering the interaction between androgens like testosterone and their target tissues. This interference can disrupt the harmonious functioning of hormones within the body.
