Chemical Structure
Description
5-Methoxy-2,3-dihydropyrrolo[2,1-b]quinazolin-9(1H)-one (C12H12N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
5-Methoxy-2,3-dihydropyrrolo[2,1-b]quinazolin-9(1H)-one (CAS 35214-99-4), molecular formula C12H12N2O2 and molecular weight 216.24 g/mol, is a CATO reference standard with documented purity and traceability.
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.
