Chemical Structure
Description
The occurrence of 1-Methyl-2-iodo-4-hydroxybenzene is closely related to a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-Methyl-2-iodo-4-hydroxybenzene (CAS 626250-54-2) 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, 1-Methyl-2-iodo-4-hydroxybenzene 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 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1-Methyl-2-iodo-4-hydroxybenzene 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.
