Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 250.05 g/mol gives 1-fluoro-2-(2-iodoethyl)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-fluoro-2-(2-iodoethyl)benzene (CAS 178685-13-7), molecular formula C8H8FI and molecular weight 250.05 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine/iodine substitution, an aromatic ring system, 1-fluoro-2-(2-iodoethyl)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 250.05 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-fluoro-2-(2-iodoethyl)benzene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
