Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(((2,4-Dimethylphenyl)thio)methyl)-2,3-dihydroimidazo[2,1-b]quinazolin-5(1H)-one (CAS 477887-35-7) is a high-purity analytical reference standard with the molecular formula C19H19N3OS and a molecular weight of 337.44 g/mol.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 3-(((2,4-Dimethylphenyl)thio)methyl)-2,3-dihydroimidazo[2,1-b]quinazolin-5(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 337.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
