Chemical Structure
Description
The occurrence of Ethyl 2-hydroxy-5-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 Ethyl 2-hydroxy-5-iodobenzoate (CAS 15125-84-5), a certified reference material (molecular formula C9H9IO3, MW 292.07 g/mol) for analytical method development and quality control.
Ethyl 2-hydroxy-5-iodobenzoate (C9H9IO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures Ethyl 2-hydroxy-5-iodobenzoate 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.
