Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 248.06 g/mol gives (4-Iodo-2-methylphenyl)methanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(4-Iodo-2-methylphenyl)methanol (CAS 1261747-54-9), molecular formula C8H9IO and molecular weight 248.06 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (4-Iodo-2-methylphenyl)methanol (C8H9IO) is characterized by a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), (4-Iodo-2-methylphenyl)methanol 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.
