4-Fluoro-1,2-diiodobenzene CAS 203059-85-2 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.

4-Fluoro-1,2-diiodobenzene (CAS 203059-85-2) is a high-purity analytical reference standard with the molecular formula C6H3FI2 and a molecular weight of 347.90 g/mol.

Owing to fluorine/iodine substitution, an aromatic ring system, 4-Fluoro-1,2-diiodobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 347.90 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).

CATO manufactures 4-Fluoro-1,2-diiodobenzene 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.
