4-Nitrosalicylic acid Chemical Properties,Uses,Production
Chemical Properties
White to yellow crystalline powder
Uses
4-Nitrosalicylic Acid is a metabolite in the degradation pathway of 2-chloro-4-nitrobenzoic acid by acinetobacter strain RKJ12.
Uses
These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
General Description
2-Hydroxy-4-nitrobenzoic acid is metabolized to 2,4-dihydroxybenzoic acid (2,4-DHBA) by a mono-oxygenase with the concomitant release of chloride and nitrite ions.
Safety Profile
Poison by intraperitoneal route.Moderately toxic by ingestion. When heated todecomposition it emits toxic vapors of NOx.
