Description

Product Detail

Product Name: 2-Chloro-4-nitroaniline (also known as o-Chloro-p-nitroaniline)
Chemical Formula: C₆H₅ClN₂O₂
CAS Number: 121-87-91

Physical Properties

Appearance: Yellow crystalline powder or yellow needle-like crystals.
Melting Point: Approximately 107–108.4 °C.
Boiling Point: Around 326.2 °C at 760 mmHg.
Density: ~1.5 g/cm³.
Solubility: Slightly soluble in water and strong acids, but readily dissolves in organic solvents such as ethanol, ether, benzene, and carbon disulfide.1

Chemical Properties

Stability & Incompatibility: Generally stable under normal conditions but incompatible with strong oxidizing agents, strong bases, and strong acids.
Flammability & Thermal Decomposition: Combustible when exposed to open flames or high heat. Upon thermal decomposition, it releases highly toxic fumes, including nitrogen oxides and hydrogen chloride gas.
Toxicity: Classified as harmful if swallowed. It can be absorbed through the skin, respiratory tract, and digestive system, causing irritation to the eyes, mucous membranes, and skin. Internally, it can induce methemoglobinemia, leading to cyanosis. Additionally, it is considered dangerous to the aquatic environment with long-lasting effects.1

Key Applications

Dye & Pigment Manufacturing: This is its primary industrial application. It serves as a crucial intermediate in the synthesis of azo dyes and organic pigments, including Pigment Scarlet R, Disperse Red GFL, Disperse Red B, and various other red/yellow dyes used extensively in the textile, leather, and paper industries.
Agrochemical Synthesis: Utilized as an important precursor in the production of pesticides and molluscicides, most notably Niclosamide (a snail-killing agent used to control schistosomiasis).
Pharmaceutical Intermediates: Acts as a building block in the synthesis of specific medicinal compounds and pharmaceutical intermediates.
