2-Amino-4,5,6,7-tetrahydrobenzo [b] thiophene-3-formamide, this substance is related to safety and toxicity, and it is an extremely critical matter. However, I have investigated it in detail in "Tiangong Kaiwu", but I have not seen its exact records. Because when "Tiangong Kaiwu" was written, modern chemical analysis techniques had not yet been developed, and it was difficult to accurately determine the safety and toxicity of specific chemical substances.
However, according to the current scientific understanding, the safety and toxicity of chemical substances must be determined through many experiments and studies. In terms of safety, it is necessary to consider whether it has potential harm to human health. If accidentally exposed, or through inhalation, ingestion, skin absorption and other routes into the human body, whether it will cause allergies, irritation, and even more serious organ damage, genetic mutation and other conditions. For example, some chemicals may irritate the skin and mucous membranes, causing discomfort in people; while some may affect the normal operation of the nervous system and immune system.
As for toxicity, there are also many types. Acute toxicity refers to the toxic reaction caused by large amounts of exposure to the substance in a short period of time, such as severe vomiting, breathing difficulties, etc. Chronic toxicity is the gradual damage to the body after long-term small exposure, such as carcinogenesis, teratogenicity, mutagenesis, etc. The harm is often more hidden and far-reaching.
To determine the safety and toxicity of 2-amino-4,5,6,7-tetrahydrobenzo [b] thiophene-3-formamide, accurate and reliable conclusions can only be reached by referring to modern professional chemical literature, relevant experimental research reports, or consulting professionals in the fields of chemistry and toxicology.
