Chemical Structure

N-Allyl-4-oxo-3-propyl-2-thioxo-1,2,3,4-tetrahydroquinazoline-7-carboxamide CAS 403727-68-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 303.38 g/mol gives N-Allyl-4-oxo-3-propyl-2-thioxo-1,2,3,4-tetrahydroquinazoline-7-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies N-Allyl-4-oxo-3-propyl-2-thioxo-1,2,3,4-tetrahydroquinazoline-7-carboxamide (CAS 403727-68-4), a certified reference material (molecular formula C15H17N3O2S, MW 303.38 g/mol) for analytical method development and quality control.

Structurally, N-Allyl-4-oxo-3-propyl-2-thioxo-1,2,3,4-tetrahydroquinazoline-7-carboxamide (C15H17N3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 303.38 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
