Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 254.45 g/mol gives 5-Chloro-2-iodophenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Chloro-2-iodophenol (CAS 136808-72-5), molecular formula C6H4ClIO and molecular weight 254.45 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 5-Chloro-2-iodophenol (C6H4ClIO) contains a hydroxyl group, an ether linkage, chlorine/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 254.45 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.
