Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 401.97 g/mol gives 4-Ethoxy-3,5-diiodobenzaldehyde distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Ethoxy-3,5-diiodobenzaldehyde (CAS 632299-37-7) is a high-purity analytical reference standard with the molecular formula C9H8I2O2 and a molecular weight of 401.97 g/mol.
The molecular framework of 4-Ethoxy-3,5-diiodobenzaldehyde (C9H8I2O2) 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. 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), 4-Ethoxy-3,5-diiodobenzaldehyde 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.
