Chemical Structure
Description
The occurrence of 1-(2-Iodoethyl)-4-methylbenzene is closely related to iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1-(2-Iodoethyl)-4-methylbenzene (CAS 120391-67-5) is a high-purity analytical reference standard with the molecular formula C9H11I and a molecular weight of 246.09 g/mol.
1-(2-Iodoethyl)-4-methylbenzene (C9H11I) contains iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-(2-Iodoethyl)-4-methylbenzene 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.
