Chemical Structure

2-Chloro-1-(4-iodophenyl)ethan-1-one CAS 4209-04-5 chemical structure

Description

The occurrence of 2-Chloro-1-(4-iodophenyl)ethan-1-one is closely related to a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Chloro-1-(4-iodophenyl)ethan-1-one (CAS 4209-04-5) is a high-purity analytical reference standard with the molecular formula C8H6ClIO and a molecular weight of 280.49 g/mol.

Owing to a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system, 2-Chloro-1-(4-iodophenyl)ethan-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 280.49 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).

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), 2-Chloro-1-(4-iodophenyl)ethan-1-one 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.
