Chemical Structure

4,6-Diiodopyrimidine CAS 19646-06-1 chemical structure

Description

Owing to a nitrile group, iodine substitution, 4,6-Diiodopyrimidine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 331.88 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

4,6-Diiodopyrimidine (CAS 19646-06-1) is a high-purity analytical reference standard with the molecular formula C4H2I2N2 and a molecular weight of 331.88 g/mol.

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), 4,6-Diiodopyrimidine 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.
