Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Iodo-3-methoxythiophene (CAS 64435-22-9) is a high-purity analytical reference standard with the molecular formula C5H5IOS and a molecular weight of 240.06 g/mol.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, iodine substitution, 2-Iodo-3-methoxythiophene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.06 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.
CATO manufactures 2-Iodo-3-methoxythiophene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
