Chemical Structure
Description
The occurrence of 5-Iodo-1H-pyrrole-2-carboxamide is closely related to an amide group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Iodo-1H-pyrrole-2-carboxamide (CAS 1936682-57-3) is a high-purity analytical reference standard with the molecular formula C5H5IN2O and a molecular weight of 236.01 g/mol.
5-Iodo-1H-pyrrole-2-carboxamide (C5H5IN2O) contains an amide group, a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 5-Iodo-1H-pyrrole-2-carboxamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
