Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 303.82 g/mol gives Difluorodiiodomethane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Difluorodiiodomethane (CAS 1184-76-5), molecular formula CF2I2 and molecular weight 303.82 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine/iodine substitution, Difluorodiiodomethane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 303.82 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), Difluorodiiodomethane 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.
