Chemical Structure
Description
The occurrence of Methyl 5-hydroxy-2-iodobenzoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Methyl 5-hydroxy-2-iodobenzoate (CAS 358672-64-7), a certified reference material (molecular formula C8H7IO3, MW 278.04 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 5-hydroxy-2-iodobenzoate (C8H7IO3) 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), Methyl 5-hydroxy-2-iodobenzoate 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.
