“…Tetrachloro-p-benzoquinone (TCBQ) is a perhalogenated quinone compound that can act as a mild oxidant and has been widely used in the fields of pharmaceuticals, the chemical industry, and pesticides. In addition, the nucleophilic substitution of TCBQ by nucleophilic substances, such as aromatic and aliphatic amines or proteins, has also been widely studied [23][24][25][26][27]. Primary and secondary aliphatic amines are known to form the disubstituted products of TCBQ, and the color of the reaction solution changes from yellow to reddish brown.…”

The detection of volatile amines is necessary due to the serious toxicity hazards they pose to human skin, respiratory systems, and nervous systems. However, traditional amines detection methods require bulky equipment, high costs, and complex measurements. Herein, we report a new simple, rapid, convenient, and visual method for the detection of volatile amines based on the gas–solid reactions of tetrachloro-p-benzoquinone (TCBQ) and volatile amines. The gas–solid reactions of TCBQ with a variety of volatile amines showed a visually distinct color in a time-dependent manner. Moreover, TCBQ can be easily fabricated into simple and flexible rapid test strips for detecting and distinguishing n-propylamine from other volatile amines, including ethylamine, n-butyamine, n-pentamine, n-butyamine and dimethylamine, in less than 3 s without any equipment assistance.
