Description

D1Q7F6C2FP 70018-51-8 Quazinone Quazinone [USAN:INN] Imidazo(2,1-b)quinazolin-2(3H)-one, 6-chloro-1,5-dihydro-3-methyl-, (R)- (R)-6-Chloro-1,5-dihydro-3-methylimidazo(2,1-b)quinazolin-2(3H)-one Quazinona [Spanish] Quazinonum [Latin] Ro 13-6438/006 Quazinona Quazinonum UNII-D1Q7F6C2FP (CAS 70018-51-8) is a high-purity analytical reference standard with the molecular formula C11H10ClN3O and a molecular weight of 235.67 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, D1Q7F6C2FP 70018-51-8 Quazinone Quazinone [USAN:INN] Imidazo(2,1-b)quinazolin-2(3H)-one, 6-chloro-1,5-dihydro-3-methyl-, (R)- (R)-6-Chloro-1,5-dihydro-3-methylimidazo(2,1-b)quinazolin-2(3H)-one Quazinona [Spanish] Quazinonum [Latin] Ro 13-6438/006 Quazinona Quazinonum UNII-D1Q7F6C2FP is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 235.67 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.
