What is 2-Nitrodiphenylamine CAS 119-75-5?

2-Nitrodiphenylamine is a nitrated aromatic amine with the molecular formula C12H10N2O2 and a molecular weight of about 214.22. It is also called 2-nitro-N-phenylaniline or o-nitrodiphenylamine and is normally supplied as a red to reddish-brown crystalline solid or powder.

What are the main industrial applications of CAS 119-75-5?

It is used primarily as an organic synthesis intermediate for dyes, pigments, pharmaceuticals, agrochemicals, and other specialty aromatic compounds. It can also be converted into 2-aminodiphenylamine for phenothiazines, azo dyes, and related fine chemicals.

How is 2-Nitrodiphenylamine used as a stabilizer?

It is used in selected industrial stabilization systems, including formulations involving nitroglycerin, propellants, synthetic rubber, plastics, and lubricants. Its controlled interaction with decomposition by-products helps improve stability in those specialized applications.

What are the key technical specifications?

Typical technical specifications include an assay of at least 98.0%, melting point around 74-76 C, boiling point near 346 C, and density about 1.36 g/cm3. The material is practically insoluble in water and soluble or slightly soluble in common organic solvents.

How should 2-Nitrodiphenylamine CAS 119-75-5 be stored?

Store it tightly closed in a cool, dry, well-ventilated area away from direct light. Keep it separated from strong oxidizers, strong acids, strong bases, and ignition sources, and use suitable gloves, goggles, protective clothing, and ventilation when handling.

How does 2-Nitrodiphenylamine differ from diphenylamine?

Diphenylamine has no nitro group, while 2-nitrodiphenylamine contains an ortho nitro substituent on one phenyl ring. That nitro group changes reactivity, polarity, and application profile, making 2-nitrodiphenylamine useful as a more specialized synthesis intermediate and stabilizer-related compound.

Storage & Safety

Store the product in a tightly closed container in a cool, dry, and well-ventilated area away from direct light. Keep it separated from strong oxidizing agents, strong acids, and strong bases. Avoid dust generation during handling. Recommended PPE includes chemical-resistant gloves, safety goggles, protective clothing, and suitable respiratory protection when ventilation is insufficient. Operators should follow standard industrial hygiene practice and avoid skin, eye, and inhalation exposure. Available SDS information also indicates irritation concerns, so routine closed handling and local exhaust ventilation are appropriate.

Quality Assurance

Quality control for 2-Nitrodiphenylamine in export-oriented production is typically based on identity confirmation and batch consistency review. Common release items include appearance, assay, melting range, and moisture or related impurity checks according to the plant’s internal specification. For higher-control programs, instrumental verification such as HPLC for purity profiling and NMR for structural confirmation can be used to support batch identity. Where the product is manufactured under formal quality systems, documentation management, retained samples, and lot traceability are usually part of standard factory control practice.
