1-Isopropyl-4-(4-isopropylphenyl)-6-(prop-2-yn-1-ylamino)quinazolin-2(1H)-one CAS 478963-46-1

Description

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 1-Isopropyl-4-(4-isopropylphenyl)-6-(prop-2-yn-1-ylamino)quinazolin-2(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 359.46 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

1-Isopropyl-4-(4-isopropylphenyl)-6-(prop-2-yn-1-ylamino)quinazolin-2(1H)-one (CAS 478963-46-1), molecular formula C23H25N3O and molecular weight 359.46 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.

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.
