Crystal structure of 1H-benzimidazole-2-carboxylic acid monohydrate_Kain Industrial Additive

Background and overview[1] 1H-benzimidazole-2-carboxylic acid crystallizes as a monohydrate and exists in the form of a zwitterion, that is, 1H-benzimidazole-2-carboxylate. In the two-dimensional network, hydrogen bonds connect the acid and water. Molecules connect. 1H-benzimidazole-2-carboxylic acid, a simple carboxylic acid first synthesized by Bistrzycki and Przeworski (1912), has not found any important applications until now. Recently,…
