Chemical Structure
Description
The occurrence of 5-Iodofuran-3-carboxylic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Iodofuran-3-carboxylic acid (CAS 1221722-85-5) is a high-purity analytical reference standard with the molecular formula C5H3IO3 and a molecular weight of 237.98 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, 5-Iodofuran-3-carboxylic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 237.98 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 5-Iodofuran-3-carboxylic acid 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.
