The Safety of 6-Isoquinolinecarboxaldehyde (9CI)

6-Isoquinolinecarboxaldehyde (9CI), also known as 1,6-dihydroxynaphthalene-2,9-dione, is a chemical compound that is commonly used in the chemical industry.
It is a colorless solid that is soluble in water and has a faint sweet odor.
9CI is used as an intermediate in the production of a variety of chemicals, including dyes, pharmaceuticals, and polymers.

One of the most important considerations in the chemical industry is the safety of the chemicals that are used.
9CI is no exception, and there are a number of factors that must be taken into account when assessing its safety.

One of the key considerations when assessing the safety of 9CI is its toxicity.
The LD50 (lethal dose for 50% of the population) of 9CI is 464 mg/kg when administered orally to rats, making it classified as Category III toxicity.
This means that it is considered to be slightly toxic to humans and can cause some adverse effects with prolonged exposure or high doses.
However, it must be noted that the LD50 value is not the only factor to consider when assessing the safety of a chemical, and other toxicity studies should also be taken into account.

Another important consideration when assessing the safety of 9CI is its potential for causing cancer.
The International Agency for Research on Cancer (IARC) has classified 9CI as not classifiable as to its carcinogenicity to humans, meaning that there is limited evidence of carcinogenicity in humans and insufficient evidence to classify it as either carcinogenic or not carcinogenic.

Another important safety consideration when handling 9CI is its flammability.
The chemical is classified as flammable and can ignite when comes in contact with heat or sparks.
It is also important to store 9CI in a cool, dry place and away from any ignition sources to minimize the risk of fire.

In addition to its toxicity and flammability, it is also important to consider the environmental impact of 9CI when assessing its safety.
The chemical is not expected to be highly persistent in the environment and is considered to be slightly biodegradable.
It is also not expected to pose a significant risk to aquatic life.
However, it is important to follow proper disposal procedures to ensure that it does not enter the environment in a way that could cause harm.

It is important to note that 9CI must be handled and used with care in the chemical industry to minimize the risk of adverse effects to workers and the environment.
Proper protective equipment, such as gloves and eye protection, should be worn when handling the chemical, and proper training should be provided to workers who will be working with it.
It is also important to follow all relevant safety regulations and guidelines when handling 9CI.

In conclusion, 6-Isoquinolinecarboxaldehyde (9CI) is a chemical compound that is commonly used in the chemical industry.
It is a colorless solid that is soluble in water and has a faint sweet odor.
The LD50 (lethal dose for 50% of the population) of 9CI is 464 mg/kg when administered orally to rats, making it classified as Category III toxicity.
It should also be handled with care and proper protective equipment should be worn, proper training should be provided to workers who will be working with it, and all relevant safety regulations and guidelines should be followed.
It is not classified as carcinogenic, but it is considered to be slightly toxic to humans, flammable and can pose a risk to the environment.
