Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 356.20 g/mol gives 5'-Iodo-m-terphenyl distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5'-Iodo-m-terphenyl (CAS 87666-86-2) is a high-purity analytical reference standard with the molecular formula C18H13I and a molecular weight of 356.20 g/mol.
Owing to iodine substitution, a polycyclic aromatic system, 5'-Iodo-m-terphenyl is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 356.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures 5'-Iodo-m-terphenyl 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.
