Pyrrole-2-carboxylic acid is a natural alkaloid derived from the marine bacterium *Pelomonas puraquae sp. Nov*. It represents a biological form of pyrrole commonly found in natural compounds. This substance serves as a precursor in biosynthetic processes for various pyrrole derivatives, including clorobiocin, coumermycin A1, pyoluteorin, leupyrrins, and undecylprodigiosin.
