Chemical Structure

3,5-Dihydroxy-4-iodobenzoic acid CAS 76447-13-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 280.02 g/mol gives 3,5-Dihydroxy-4-iodobenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3,5-Dihydroxy-4-iodobenzoic acid (CAS 76447-13-7), a certified reference material (molecular formula C7H5IO4, MW 280.02 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system, 3,5-Dihydroxy-4-iodobenzoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.02 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.

As a certified reference material (CRM), 3,5-Dihydroxy-4-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.
