Methyl 4-hydroxy-3,5-diiodobenzoate CAS 3337-66-4

Description

Compared with other compounds in its class, the molecular weight of 403.94 g/mol gives Methyl 4-hydroxy-3,5-diiodobenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Methyl 4-hydroxy-3,5-diiodobenzoate (CAS 3337-66-4), a certified reference material (molecular formula C8H6I2O3, MW 403.94 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, Methyl 4-hydroxy-3,5-diiodobenzoate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 403.94 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), Methyl 4-hydroxy-3,5-diiodobenzoate 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.
