Understanding Glacial Acetic Acid CAS Number and Applications

Glacial acetic acid, known chemically as ethanoic acid, is a colorless liquid organic compound with the formula CH₃COOH. The term glacial refers to its pure form that occurs below a temperature of 16.6°C, where it solidifies into ice-like crystals. The CAS number for glacial acetic acid is 64-19-7, a unique identifier used universally to identify chemical substances. This number is critical in regulatory filings, research, and industry applications as it ensures precise communication about the substance.

In addition to its industrial applications, glacial acetic acid is also prevalent in laboratories as a reagent. It plays a significant role in organic synthesis and serves as a solvent for various chemical reactions. Furthermore, because of its acidity, it is used in the preparation of buffer solutions, which help maintain pH levels in biochemical research.

Glacial acetic acid has significant applications in the food industry as well. It is commonly used as a preservative and flavoring agent. In its diluted form, it is recognized as vinegar, which is widely used in culinary practices around the world. The acidity of acetic acid inhibits microbial growth, making it an effective preservative for pickling and fermenting foods.

Safety measures are paramount when handling glacial acetic acid due to its corrosive nature. Exposure can lead to irritation of the skin, eyes, and respiratory system, necessitating the use of appropriate personal protective equipment (PPE) during handling and storage. Proper ventilation and the use of safety equipment are crucial in both industrial and laboratory settings to prevent accidents.

In conclusion, glacial acetic acid, identified by the CAS number 64-19-7, is an essential chemical with vast applications in various industries. Its versatility ranges from chemical manufacturing to food preservation, highlighting its significance in both commercial and scientific domains. As with any chemical, understanding its properties and ensuring safe handling practices are vital for utilizing glacial acetic acid effectively.
