Chemical Structure
Description
As a certified reference material (CRM), 3-(4-Hydroxy-3,5-diiodophenyl)-2-phenylpropanoic acid 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.
CATO supplies 3-(4-Hydroxy-3,5-diiodophenyl)-2-phenylpropanoic acid (CAS 577-91-3), a certified reference material (molecular formula C15H12I2O3, MW 494.06 g/mol) for analytical method development and quality control.
The molecular framework of 3-(4-Hydroxy-3,5-diiodophenyl)-2-phenylpropanoic acid (C15H12I2O3) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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.
