Glacial acetic acid CAS number.
The Role of Glacial Acetic Acid in the CAS System
The Chemical Abstracts Service (CAS) is a renowned database that catalogs and indexes information on chemical substances, including their structures, properties, and biological activities. One of the key components used in this system is glacial acetic acid, which plays a crucial role in the identification and classification of chemicals.
Glacial acetic acid, also known as pure acetic acid or glacial ethanoic acid, is a colorless liquid with a sharp, pungent odor. It is a weak organic acid with a molecular formula of C2H4O2 and a molar mass of 60.05 g/mol. This compound is commonly used in various industrial processes, such as the production of vinyl acetate, acetic anhydride, and cellulose acetate.
In the CAS system, glacial acetic acid serves as a reference substance for the assignment of CAS numbers to other chemicals. A CAS number is a unique identifier assigned to each chemical substance in the database. It consists of a seven-digit number followed by a check digit, which is calculated using a specific algorithm. When a new chemical is added to the CAS system, its structure is analyzed, and a CAS number is assigned based on its structural relationships with other chemicals in the database When a new chemical is added to the CAS system, its structure is analyzed, and a CAS number is assigned based on its structural relationships with other chemicals in the database

Glacial acetic acid is particularly useful as a reference substance because it is a well-known and widely used chemical. Its presence in the CAS system helps to ensure the accuracy and consistency of the data associated with other chemicals. By using glacial acetic acid as a starting point, chemists can more easily navigate the vast array of substances contained within the CAS database and locate the information they need.
Moreover, glacial acetic acid's role in the CAS system extends beyond its use as a reference substance. It is also used in the calculation of molecular weights and other physical properties of chemicals. This information is essential for understanding the behavior and properties of chemicals and for developing new applications and uses for them.
In conclusion, glacial acetic acid is a vital component of the CAS system, serving as a reference substance for the assignment of CAS numbers and aiding in the calculation of molecular weights and other physical properties of chemicals. Its widespread use and well-established properties make it an indispensable tool for chemists and other scientists working with chemical substances.
