For chemists, researchers, and production managers, a thorough understanding of the chemical properties and safe handling procedures for any compound is fundamental. 1,4-Diamino-2-nitrobenzene (CAS 5307-14-2), a versatile organic intermediate, is no exception. This article delves into its key physical and chemical characteristics, along with essential safety information to ensure its effective and secure use in laboratory and industrial settings.

Understanding the Chemical Profile

1,4-Diamino-2-nitrobenzene, with the molecular formula C6H7N3O2, has a molecular weight of approximately 153.14 g/mol. Key physical properties include:

  • Appearance: Typically described as a brown to black powder.
  • Melting Point: Reported in literature to be around 135-138 °C, indicating it is a solid at room temperature.
  • Solubility: It exhibits limited solubility in water, with values around 0.2 g/L. However, it may be soluble in certain organic solvents.
  • Density: Estimated around 1.3682 g/cm³.

Chemically, the presence of two amine groups and a nitro group on the benzene ring makes it reactive. The amine groups can undergo electrophilic substitution and diazotization reactions, while the nitro group is electron-withdrawing and can be reduced to an amino group. This reactivity makes it valuable as an intermediate in the synthesis of dyes and pharmaceuticals.

Safety and Handling Precautions

As with many aromatic amines and nitro compounds, 1,4-Diamino-2-nitrobenzene should be handled with care. Comprehensive safety data sheets (SDS) should always be consulted before use. General precautions include:

  • Personal Protective Equipment (PPE): Always wear appropriate PPE, including chemical-resistant gloves, safety goggles or a face shield, and protective clothing to prevent skin and eye contact.
  • Ventilation: Handle in a well-ventilated area or under a fume hood to minimize inhalation of dust or vapors.
  • Storage: Store in a cool, dry, and dark place, preferably in an inert atmosphere, away from incompatible materials such as strong oxidizing agents.
  • Incompatibilities: Avoid contact with strong acids, strong bases, and oxidizing agents, which could lead to hazardous reactions.

Procurement and Quality Assurance

When you need to purchase 1,4-Diamino-2-nitrobenzene (CAS 5307-14-2), it is essential to source from reputable manufacturers and suppliers. Checking the availability and current 1,4-Diamino-2-nitrobenzene price from reliable sources, especially manufacturers in China, is recommended. Ensuring the product comes with a detailed SDS and CoA from the supplier is crucial for safe handling and quality verification in your laboratory or production facility.
