Nitroso R

Description:

Nitroso R, also known as 4-nitrosoaniline, is an organic compound characterized by the presence of a nitroso group (-NO) attached to an aniline structure. It typically appears as a yellow to orange crystalline solid and is known for its aromatic properties. The compound is soluble in organic solvents but has limited solubility in water. Nitroso R is primarily used in organic synthesis and as an intermediate in the production of dyes and pigments. It exhibits reactivity typical of nitroso compounds, including the ability to participate in electrophilic aromatic substitution reactions. Additionally, it can undergo reduction to form corresponding amines. Safety considerations are important when handling this compound, as nitroso compounds can be toxic and potentially carcinogenic. Proper laboratory protocols should be followed to minimize exposure and ensure safe handling. Overall, Nitroso R serves as a valuable building block in various chemical applications, particularly in the field of dye chemistry.

Disodium 1-Nitroso-2-naphthol-3,6-disulfonate Monohydrate

CAS: 525-05-3

Disodium 1-nitroso-2-naphthol-3,6-disulfonate monohydrate is a chemical compound that has been used as an analytical reagent in the determination of the optimal reaction conditions for the reduction of nitroso compounds. Disodium 1-nitroso-2-naphthol-3,6-disulfonate monohydrate can be synthesized by reacting hydrochloric acid with cationic surfactant and pharmaceutical preparations. The redox potentials are determined by the pH of the solutions, which in turn depend on the concentration of sodium citrate and dimethylformamide. This product is stable in water at room temperature but decomposes at higher temperatures. It also reacts with copper to form stable complexes with electron reduction. Disodium 1-nitroso-2-naphthol-3,6-disulfonate monohydrate can be synthesized by reacting hydrochloric acid with cationic
