Description

2 : 4-Dinitrochlorobenzene (DNCB) is a chemical compound used primarily in the production of dyes and as an intermediate in organic synthesis. It is a yellow crystalline solid that is soluble in organic solvents but insoluble in water. DNCB is known for its strong odor and is classified as a skin sensitizer, meaning it can cause allergic reactions upon contact with the skin. Due to its sensitizing properties, DNCB has also been used in immunological research as a reagent for the detection of T lymphocytes. However, its use has declined over the years due to safety concerns and the availability of alternative compounds.
