Chemical Structure
Description
As a certified reference material (CRM), 2-amino-5-iodobenzoic 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 2-amino-5-iodobenzoic acid (CAS 5326-47-6), a certified reference material (molecular formula C7H6INO2, MW 263.03 g/mol) for analytical method development and quality control.
The molecular framework of 2-amino-5-iodobenzoic acid (C7H6INO2) is characterized by an amide group, 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 protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
