Chemical Structure
Description
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.
2,5-Diiodo-3-methylthiophene (CAS 16488-60-1) is a high-purity analytical reference standard with the molecular formula C5H4I2S and a molecular weight of 349.96 g/mol.
Owing to sulfur-containing functionality, iodine substitution, 2,5-Diiodo-3-methylthiophene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 349.96 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 2,5-Diiodo-3-methylthiophene 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.
