2,5-Bis(hydroxymethyl)pyrrole is an organic chemical compound with formula C₆H₉O₂N, or (HOCH₂)₂(C₄H₃N). Its molecule can be described as that of pyrrole C₄H₅N with hydroxymethyl groups HO−CH₂− replacing the two hydrogen atoms adjacent to the nitrogen atom.

The compound is a white solid, soluble in water and acetone. It is stable in alkaline solutions, but otherwise tends to polymerize by self-condensation.^[1] The compound was used as an intermediate in the synthesis of hexahydroporphine ("unsubstituted porphyrinogen"),^[1] the core of uroporphyrinogen III, precursor of many critically important biological products such as hemoglobin and chlorophyll.

Preparation[edit]

The compound can be synthesized by formylation of pyrrole followed by reduction of the resulting pyrrolecarboxaldehyde.^[1]
