Chemical Structure
Description
The occurrence of 2,3,4,5-Tetraiodo-1H-pyrrole is closely related to a nitrile group, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2,3,4,5-Tetraiodo-1H-pyrrole (CAS 87-58-1), a certified reference material (molecular formula C4HI4N, MW 570.68 g/mol) for analytical method development and quality control.
Based on its molecular formula C4HI4N, 2,3,4,5-Tetraiodo-1H-pyrrole contains a nitrile group, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 570.68 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
