Chemical Structure

4-Chloro-2-iodobenzoic acid CAS 13421-13-1 chemical structure

Description

As a certified reference material (CRM), 4-Chloro-2-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 4-Chloro-2-iodobenzoic acid (CAS 13421-13-1), a certified reference material (molecular formula C7H10ClIO2, MW 288.51 g/mol) for analytical method development and quality control.

The molecular framework of 4-Chloro-2-iodobenzoic acid (C7H10ClIO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/iodine substitution. 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.

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.
