General Description |
Thionitrobenzoic acid, also known as 2-Nitrobenzenethiol, is a compound with the chemical formula C7H5NO3S. It is a yellow crystalline solid that is commonly used in organic synthesis and as a reagent in chemical reactions. Thionitrobenzoic acid is known for its use as a colorimetric reagent for the detection of various metal ions, such as copper, mercury, and zinc. It is also used in the determination of the concentration of proteins in biological samples. Thionitrobenzoic acid has a strong odor and is toxic if ingested or inhaled, and can cause irritation to the skin and eyes. Due to its potential hazards, it should be handled and stored with caution. |
