Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-{[(2-chloro-6-fluorophenyl)methyl]sulfanyl}-8,9-dimethoxy-3-(propan-2-yl)-2H,3H-imidazo[1,2-c]quinazolin-2-one.
CATO supplies 5-{[(2-chloro-6-fluorophenyl)methyl]sulfanyl}-8,9-dimethoxy-3-(propan-2-yl)-2H,3H-imidazo[1,2-c]quinazolin-2-one (CAS 1024594-03-3), a certified reference material (molecular formula C22H21ClFN3O3S, MW 461.94 g/mol) for analytical method development and quality control.
Structurally, 5-{[(2-chloro-6-fluorophenyl)methyl]sulfanyl}-8,9-dimethoxy-3-(propan-2-yl)-2H,3H-imidazo[1,2-c]quinazolin-2-one (C22H21ClFN3O3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 461.94 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
