FAQ

What are the physical and chemical properties of Sodium (~15~N)nitrite (CAS: 68378-96-1)?

Sodium (~15~N)nitrite (CAS: 68378-96-1) is a crystalline solid with a molecular weight of approximately 84.01 g/mol. It is highly soluble in water (192.4 g/100 mL at 20°C) and has a pungent odor similar to other nitrites. It is reactive, especially with strong acids, which can cause the release of nitrogen oxides and nitrogen gas. It is also unstable at high temperatures and can decompose to form sodium nitrate and nitrogen.

How is Sodium (~15~N)nitrite (CAS: 68378-96-1) typically synthesized?

Sodium (~15~N)nitrite (CAS: 68378-96-1) is typically synthesized by the reaction of sodium nitrate with aqueous ammonia. The process involves dissolving sodium nitrate in water and then adding aqueous ammonia to produce sodium (~15~N)nitrite. This reaction is selective and yields a high purity product under controlled conditions.

What industries use Sodium (~15~N)nitrite (CAS: 68378-96-1)?

Sodium (~15~N)nitrite (CAS: 68378-96-1) is used in various industries, including pharmaceuticals, where it serves as a reagent in drug synthesis and as a preservative. It is also used in the production of food additives, as a reducing agent in polymers, and in the development of sensors and semiconductors, where its reactivity plays a critical role.

What precautions should be taken when handling Sodium (~15~N)nitrite (CAS: 68378-96-1)?

When handling Sodium (~15~N)nitrite (CAS: 68378-96-1), it is crucial to wear appropriate personal protective equipment (PPE) such as gloves, safety goggles, and a laboratory coat. Handle in a well-ventilated area or fume hood to avoid inhalation of dust. Store in a cool, dry place away from strong acids and heat sources. In case of spill, immediately clean up using appropriate absorbent materials and consult the Material Safety Data Sheet (MSDS) for further instructions.
