Chemical Structure

3-Iodo-5-methylphenol CAS 1073339-05-5 chemical structure

Description

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.

3-Iodo-5-methylphenol (CAS 1073339-05-5) is a high-purity analytical reference standard with the molecular formula C7H7IO and a molecular weight of 234.03 g/mol.

Owing to a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system, 3-Iodo-5-methylphenol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 234.03 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), 3-Iodo-5-methylphenol 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.
