Chemical Structure
Description
The occurrence of Pyrrole-3-carboxylic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Pyrrole-3-carboxylic acid (CAS 931-03-3) is a high-purity analytical reference standard with the molecular formula C5H5NO2 and a molecular weight of 111.10 g/mol.
Based on its molecular formula C5H5NO2, Pyrrole-3-carboxylic acid contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 111.10 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
