Chemical Structure
Description
5-Chloro-2-iodo-3-methylphenol (CAS 1150617-66-5) is a high-purity analytical reference standard with the molecular formula C7H6ClIO and a molecular weight of 268.48 g/mol.
The molecular framework of 5-Chloro-2-iodo-3-methylphenol (C7H6ClIO) is characterized by a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
As a certified reference material (CRM), 5-Chloro-2-iodo-3-methylphenol 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.
