Chemical Structure

2,6-Diiodo-7H-purine CAS 98027-95-3 chemical structure

Description

2,6-Diiodo-7H-purine (CAS 98027-95-3), molecular formula C5H2I2N4 and molecular weight 371.91 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrile group, iodine substitution, 2,6-Diiodo-7H-purine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 371.91 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.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
