Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 307.99 g/mol gives 1,3-Difluoro-5-iodo-2-(trifluoromethyl)benzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,3-Difluoro-5-iodo-2-(trifluoromethyl)benzene (CAS 910787-71-2), molecular formula C7H2F5I and molecular weight 307.99 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1,3-Difluoro-5-iodo-2-(trifluoromethyl)benzene (C7H2F5I) contains fluorine/iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 307.99 g/mol, it falls into the moderately-high-molecular-weight range. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
