Chemical Structure

1-azido-2,3,5-triiodobenzene CAS 1313738-68-9 chemical structure

Description

As a certified reference material (CRM), 1-azido-2,3,5-triiodobenzene 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.

1-azido-2,3,5-triiodobenzene (CAS 1313738-68-9), molecular formula C6H8I3N3 and molecular weight 502.86 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-azido-2,3,5-triiodobenzene (C6H8I3N3) is characterized by a nitrile group, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
