Chemical Structure

2,6-Dichloroiodobenzene CAS 19230-28-5 chemical structure

Description

As a certified reference material (CRM), 2,6-Dichloroiodobenzene 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.

2,6-Dichloroiodobenzene (CAS 19230-28-5) is a high-purity analytical reference standard with the molecular formula C6H3Cl2I and a molecular weight of 272.90 g/mol.

Structurally, 2,6-Dichloroiodobenzene (C6H3Cl2I) contains chlorine/iodine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 272.90 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
