Chemical Structure

3,5-Diiodoaniline CAS 35122-96-4 chemical structure

Description

3,5-Diiodoaniline (CAS 35122-96-4), molecular formula C6H5I2N and molecular weight 344.92 g/mol, is a CATO reference standard with documented purity and traceability.

3,5-Diiodoaniline (C6H5I2N) contains a nitrile group, 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).

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), 3,5-Diiodoaniline 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.
