Use	Used as analytical reagent and organic synthesis intermediate.
Production method	Made by heating and refluxing α-naphthylthiourea in chlorobenzene. Add α-naphthylthiourea to chlorobenzene, heat and reflux to dissolve, and continue to reflux for 8 hours. After recovering chlorobenzene under reduced pressure, it is cooled and crystallized, extracted with hexane, recovered hexane, and obtained crude product. After recrystallization with acetone, the finished product is obtained with a yield of more than 85%.
