    Product Description

    2-Nitrodiphenylamine CAS 119-75-5, also called 2-nitro-N-phenylaniline, is a nitrated aromatic amine with the molecular formula C12H10N2O2 and EINECS 204-348-6.

    Synonyms: 2-Nitro-N-phenylaniline; N-phenyl-o-nitroaniline; Phenyl 2-nitrophenylamine; Benzenamine, 2-nitro-N-phenyl-; o-Nitrodiphenylamine.

    CAS: 119-75-5.

    Molecular formula: C12H10N2O2.

    It is a red to reddish-brown crystalline solid or powder with an assay of not less than 98.0%.

    Melting point is about 74-76 °C, boiling point about 346 °C, and density about 1.36 g/cm³.

    It is practically insoluble in water and slightly soluble in chloroform, DMSO, and methanol.

    It is used primarily as an organic-synthesis intermediate for dyes, pigments, pharmaceuticals, agrochemicals, and other specialty aromatic compounds.

    It can be converted into 2-aminodiphenylamine for phenothiazines, azo dyes, and related fine chemicals.

    In selected industrial stabilization systems it interacts with decomposition by-products in formulations involving nitroglycerin, propellants, synthetic rubber, plastics, and lubricants.

    In R&D and process use it is a reference material for aromatic substitution chemistry and an intermediate for dye and specialty-additive screening.

    It is applicable to research-scale and pilot-scale process screening for nitrated aromatic compounds.

    Store tightly closed in a cool, dry, well-ventilated area away from direct light, and separated from strong oxidizers, strong acids, strong bases, and ignition sources.

    Avoid dust generation and wear chemical-resistant gloves, safety goggles, protective clothing, and suitable respiratory protection when ventilation is insufficient.

    Use routine closed handling and local exhaust ventilation to avoid skin, eye, and inhalation exposure.

    Every batch is controlled by identity confirmation, assay, melting range, and moisture or related-impurity checks, with HPLC and NMR support where required.

    Confirm appearance, assay, melting point, moisture, related impurities, packaging, and grade as required.

    FAQ - Technical & Supply Chain

    • Q:

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

      A: 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.
    • Q:

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

      A: 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.
    • Q:

      How is 2-Nitrodiphenylamine used as a stabilizer?

      A: 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.
    • Q:

      What are the key technical specifications?

      A: 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.
    • Q:

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

      A: 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.
    • Q:

      How does 2-Nitrodiphenylamine differ from diphenylamine?

      A: 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.
