Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 281.09 g/mol gives 3-(4-Iodophenyl)pyridine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(4-Iodophenyl)pyridine (CAS 78313-73-2), molecular formula C11H8IN and molecular weight 281.09 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(4-Iodophenyl)pyridine (C11H8IN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, iodine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 281.09 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 3-(4-Iodophenyl)pyridine 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.
