What is the CAS number and UN dangerous goods number of butanone?

CAS Number of Butanone and UN Dangerous Goods Number: Analysis and Application

in the chemical industry, butanone, as an important organic compound, is widely used in solvents, coatings, pharmaceuticals and other fields. Knowing the CAS number and UN dangerous goods number of butanone not only helps us to better understand its chemical properties, but also ensures its safety and compliance during transportation and storage.

Basic information of butanone

Butanone, the chemical name is methyl ethyl ketone, is a colorless, flammable liquid with a special odor. Its chemical formula is C, H, O, and its structural formula is (CH) CO. Butanone is liquid at room temperature, with a boiling point of 56.5°C and a density of about 0.81g/cm³. These physical properties make it a popular choice in the solvent and coating industries.

CAS number for butanone

In the field of chemistry, the CAS number (Chemical Abstracts Service Number) is a numbering system that uniquely identifies chemical substances and is assigned by the United States Chemical Abstracts Service (CAS). The CAS number for butanone is 78-93-3. This number is used worldwide to help scientists, researchers and industry quickly find and cite literature, data and use cases related to butanone.

The uniqueness of CAS number lies in its uniqueness and authority. Whether in academic research or industrial applications, CAS numbers are the standard tool for identifying chemical substances. Through the CAS number, users can find detailed chemical information in the CAS database, including the structure, properties, synthesis methods and application fields of butanone.

UN Dangerous Goods Number

In addition to the CAS number, butanone is subject to the regulations for dangerous goods during transport. According to the United Nations Recommendations on the Transport of Dangerous Goods (UN TDG), butanone is classified as a flammable liquid and its UN dangerous goods number is UN 1189. This number is important in the global transport of dangerous goods, ensuring the safety and compliance of butanone during transportation.

The role of the UN number is to provide a uniform identification so that customs, transport companies and relevant authorities can quickly identify dangerous goods and take appropriate security measures. As butanone is a flammable liquid, the UN 1189 number indicates its potential fire risk, so it is necessary to use qualified packaging and means of transportation to ensure that there will be no leakage or fire accident.

Meaning of CAS and UN Numbers of Butanone

CAS number and UN number of butanone have important practical value in chemical industry. The CAS number provides a standardized basis for the identification and research of butanone, enabling scientists from different countries and regions to easily communicate and share research results. The UN number ensures the safety and compliance of butanone in the transport of dangerous goods, reducing potential risks during transport.

The combination of these two numbers not only improves the standardization level of butanone in industrial applications, but also provides an important reference tool for related enterprises and researchers. Whether it is research in the laboratory or transportation and storage in industrial production, the CAS number and UN number of butanone are indispensable information.

Conclusion

As an important chemical raw material, butanone CAS 78-93-3 and UN dangerous goods number 1189 play a key role in the industry. These numbers not only help us better identify and understand the chemical properties of butanone, but also ensure its safety and compliance during transportation and storage. For professionals in the chemical industry, mastering this information is an important foundation to ensure that the work is carried out smoothly.
