Potassium nitrate

Description:

Potassium nitrate, with the chemical formula KNO₃ and CAS number 7757-79-1, is an inorganic compound that appears as a white crystalline solid. It is highly soluble in water and exhibits a salty taste. This compound is known for its role as a fertilizer, providing essential nutrients, particularly nitrogen and potassium, to plants. Additionally, potassium nitrate is utilized in food preservation, particularly in curing meats, due to its ability to inhibit bacterial growth. It also serves as an oxidizing agent in various chemical reactions and is a key component in the production of gunpowder and fireworks. The substance has a high melting point and decomposes upon heating, releasing nitrogen oxides and potassium oxide. In terms of safety, potassium nitrate is generally considered non-toxic but can pose hazards if ingested in large quantities or if it comes into contact with strong acids, which can lead to the release of toxic gases. Overall, potassium nitrate is a versatile compound with significant applications in agriculture, food processing, and pyrotechnics.

Controlled Product

CAS: 7757-79-1

Potassium nitrate is a salt of potassium and nitrate. It is used in the food industry as a preservative, and it has been shown to be an effective antimicrobial agent. Potassium nitrate has been shown to inhibit the growth of oral pathogens, such as cariogenic bacteria, in a model system. This compound also has insecticidal properties. Potassium nitrate inhibits the development of insects by interfering with their ability to synthesize proteins necessary for metamorphosis from larvae to pupae and from pupae to adults.
