Chemical Structure

1-Chloro-3-iodo-5-methylbenzene CAS 116632-43-0 chemical structure

Description

The occurrence of 1-Chloro-3-iodo-5-methylbenzene is closely related to chlorine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-Chloro-3-iodo-5-methylbenzene (CAS 116632-43-0), a certified reference material (molecular formula C7H6ClI, MW 252.48 g/mol) for analytical method development and quality control.

Based on its molecular formula C7H6ClI, 1-Chloro-3-iodo-5-methylbenzene contains chlorine/iodine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 252.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

CATO manufactures 1-Chloro-3-iodo-5-methylbenzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
