Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 294.09 g/mol gives 1-Iodo-2,4,5-trimethoxybenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-Iodo-2,4,5-trimethoxybenzene (CAS 23149-33-9) is a high-purity analytical reference standard with the molecular formula C9H11IO3 and a molecular weight of 294.09 g/mol.
The molecular framework of 1-Iodo-2,4,5-trimethoxybenzene (C9H11IO3) is characterized by a carboxylic acid group, 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 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.
CATO manufactures 1-Iodo-2,4,5-trimethoxybenzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
