Compared with other compounds in its class, the molecular weight of 376.19 g/mol gives 6-Iodo-3-(4-methylbenzyl)quinazolin-4(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
6-Iodo-3-(4-methylbenzyl)quinazolin-4(3H)-one (CAS 302913-33-3), molecular formula C16H13IN2O and molecular weight 376.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution, 6-Iodo-3-(4-methylbenzyl)quinazolin-4(3H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 376.19 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.
