Chemical Structure
Description
The occurrence of 2-Iodo-1H-pyrrole-3-carbaldehyde 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.
2-Iodo-1H-pyrrole-3-carbaldehyde (CAS 35302-92-2), molecular formula C5H4INO and molecular weight 221.00 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C5H4INO, 2-Iodo-1H-pyrrole-3-carbaldehyde contains an amide group, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 221.00 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Iodo-1H-pyrrole-3-carbaldehyde 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.
