Chemical Structure
Description
Structurally, (4-Chloro-2-iodophenyl)methanol (C7H6ClIO) 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 268.48 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).
(4-Chloro-2-iodophenyl)methanol (CAS 244104-55-0) is a high-purity analytical reference standard with the molecular formula C7H6ClIO and a molecular weight of 268.48 g/mol.
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.
