Description
As a certified reference material (CRM), 1-Fluoro-4-(iodomethyl)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.
1-Fluoro-4-(iodomethyl)benzene (CAS 3831-29-6), molecular formula C7H6FI and molecular weight 236.03 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Fluoro-4-(iodomethyl)benzene (C7H6FI) 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 236.03 g/mol, it falls into the medium-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.
