Understanding CAS No. 139-07-1 A Comprehensive Overview

The chemical compound associated with CAS No. 139-07-1 is commonly known as 1,2-Benzanthracene. This polycyclic aromatic hydrocarbon (PAH) is a significant subject of study due to its implications in environmental science, toxicology, and industrial applications.

Chemical Structure and Properties

1,2-Benzanthracene is a polycyclic aromatic hydrocarbon, meaning it is made up of multiple fused aromatic rings. Its structure consists of three fused benzene rings, which gives it a planar structure conducive to various chemical interactions. This compound has a high molecular weight and is characterized by its stability, which is often a feature of PAHs. The chemical formula for 1,2-Benzanthracene is C18H12, and it has a melting point of about 105 °C, as well as a boiling point around 405 °C.

Sources and Occurrence

1,2-Benzanthracene is primarily formed through the incomplete combustion of organic materials. It can be found in coal tar, crude oil, and as a byproduct of various industrial processes. Additionally, it is present in cigarette smoke and grilled meats due to the pyrolysis of organic matter. The environmental occurrence of this compound raises concerns regarding its potential effects on ecosystems and human health.

Health Implications and Toxicology

Research has indicated that 1,2-Benzanthracene is a potent carcinogen. It has been associated with various forms of cancer, particularly in laboratory animals used for toxicological studies. Its mechanism of action involves metabolic activation, wherein it is transformed into reactive intermediates that can bind to DNA, inducing mutations. This characteristic is a primary reason for its classification as a Group 2A carcinogen by the International Agency for Research on Cancer (IARC), indicating that it is probably carcinogenic to humans.

Due to its potential harmful effects, 1,2-Benzanthracene has been the focus of environmental monitoring, particularly in urban areas with high levels of vehicular emissions or industrial activities. The persistence of this compound in the environment poses challenges for public health and safety measures, necessitating rigorous regulatory practices.

Regulatory and Safety Considerations

Regulations surrounding 1,2-Benzanthracene vary by country but generally fall under strict environmental protection guidelines due to its carcinogenic properties. Agencies such as the Environmental Protection Agency (EPA) and the IARC have established limits and monitoring protocols for PAHs, including 1,2-Benzanthracene, to mitigate exposure risks and protect public health.

In laboratory and industrial settings, proper safety measures must be in place to handle this compound. Personal protective equipment (PPE), fume hoods, and safe disposal methods are essential when working with substances that may contain or generate 1,2-Benzanthracene.

Conclusion

CAS No. 139-07-1, or 1,2-Benzanthracene, serves as a crucial reminder of the intersection between chemistry, public health, and environmental stewardship. Understanding its properties, sources, and health implications is vital for researchers, regulatory bodies, and the public to develop effective strategies for minimizing exposure and mitigating risks associated with this hazardous chemical. As we face ongoing challenges related to pollution and health, awareness and education about compounds like 1,2-Benzanthracene remain paramount.
