Glacial acetic acid's CAS number refers to its unique chemical identifier.

Understanding Glacial Acetic Acid A Comprehensive Look at its CAS Number and Significance Glacial acetic acid, a term that might evoke images of icy coldness, is actually a pure form of vinegar's main component, acetic acid. The term 'glacial' refers to its solid, crystalline state at room temperature, devoid of water or impurities. Its scientific identity lies in its CAS (Chemical Abstracts Service) number, which is a unique identifier assigned to chemical substances. The CAS number for glacial acetic acid is 64-19-7, a code that serves as a universal language in the world of chemistry. CAS numbers are administered by the American Chemical Society's CAS division, and they help chemists and researchers globally to accurately identify and communicate about chemicals. Each digit in the CAS number represents a specific piece of information. The first part, 64, identifies the substance's basic group, the second part, 19, denotes the sequence number within that group, and the final digit, 7, is a check digit for validation. Glacial acetic acid, with its CAS number 64-19-7, is a colorless, pungent-smelling chemical compound primarily composed of carbon, hydrogen, and oxygen. It has a molecular formula of C2H4O2 and is highly versatile, finding applications in various industries including pharmaceuticals, food processing, and chemical synthesis. In the pharmaceutical industry, glacial acetic acid is used as an excipient, a substance that aids in the formulation or manufacturing of a drug. In food processing, it serves as a flavoring agent and preservative In food processing, it serves as a flavoring agent and preservative In food processing, it serves as a flavoring agent and preservative In food processing, it serves as a flavoring agent and preservativeglacial acetic acid cas number. Its acidic nature also makes it useful in chemical reactions, where it can act as a solvent or a reagent, contributing to the formation of other compounds. Its 'glacial' prefix is derived from the fact that when acetic acid is purified to remove all water, it forms a solid that appears clear like ice, hence the term 'glacial'. This purity is critical, as impurities can alter the properties and effectiveness of the acid in various applications. Understanding the CAS number 64-19-7 is crucial for safety, regulation, and research purposes. It ensures that the glacial acetic acid being used is the intended substance, reducing the risk of errors or adverse reactions. Furthermore, this identification number enables tracking of the compound through supply chains, ensuring quality control and compliance with safety regulations. In conclusion, glacial acetic acid, with its CAS number 64-19-7, is a fundamental chemical compound with a wide range of uses. Its unique identifier serves as a bridge between researchers, manufacturers, and regulators, fostering effective communication and ensuring the safe and accurate use of this important chemical in numerous industrial processes.
