Ensulizole (INN; [1] also known as phenylbenzimidazole sulfonic acid) is a common sunscreen agent. In 1999, the United States Food and Drug Administration regulated that the name ensulizole be used on sunscreen labels in the United States.
Benzimidazole is a base: C 6 H 4 N(NH)CH + H + → [C 6 H 4 (NH) 2 CH] + It can also be deprotonated with stronger bases: C 6 H 4 N(NH)CH + LiH → Li [C 6 H 4 N 2 CH] + H 2. The imine can be alkylated and also serves as a ligand in coordination chemistry. The most prominent benzimidazole complex features N-ribosyl-dimethylbenzimidazole, as ...
2-Aminothiophenol is an organosulfur compound with the formula C 6 H 4 (SH)(NH 2). It is a colorless oily solid, although impure samples can be deeply colored. It is soluble in organic solvents and in basic water. 2-Aminothiophenol is a precursor to benzothiazoles, some of which are bioactive or are commercial dyes.
