Sodium 2-Nitrophenolate (NaONP) – CAS 824-39-5

About the Product

Sodium 2-nitrophenolate, also called nitrophenolate sodium, is the sodium salt of 2-Nitrophenol. It is sometimes referred to as sodium ortho nitrophenolate because the nitro group (-NO₂) is at the ortho position relative to the hydroxyl group on the benzene ring. This compound combines the properties of phenol derivatives with sodium ions, resulting in enhanced solubility and reactivity.

• Appearance: Bright red crystalline solid
• Solubility: Highly soluble in water
• Structure: The structure of sodium phenate shows a benzene ring with a nitro group in ortho position and a phenolate (-O⁻) group attached to sodium (Na⁺).

This combination gives the compound both phenolic and ionic properties, making it versatile for multiple industrial applications.

Synthesis Methods

Sodium 2-nitrophenolate is synthesized mainly through the following methods:

1. 1. Reaction with Sodium Hydroxide:2-Nitrophenol reacts with sodium hydroxide (NaOH) in aqueous solution, replacing the hydrogen atom of the hydroxyl group with sodium, forming sodium nitrophenolate.
2. 2. Reaction with Ortho Nitro Chloro Benzene (ONCB):Another process involves reacting Ortho Nitro Chloro Benzene with NaOH under controlled temperature conditions to yield sodium ortho nitrophenolate.
