Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Iodoselenophene.
3-Iodoselenophene (CAS 18168-61-1) is a high-purity analytical reference standard with the molecular formula C4H3ISe and a molecular weight of 256.93 g/mol.
Owing to iodine substitution, 3-Iodoselenophene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 256.93 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures 3-Iodoselenophene 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.
