Description
CATO supplies 2-Iodo-5-phenylthiophene (CAS 13781-37-8), a certified reference material (molecular formula C10H7IS, MW 286.13 g/mol) for analytical method development and quality control.
Owing to sulfur-containing functionality, iodine substitution, an aromatic ring system, 2-Iodo-5-phenylthiophene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 286.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 2-Iodo-5-phenylthiophene 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.
