2,4-Dihydro-4-pentyl-1-thioxo[1,2,4]triazolo[4,3-a]quinazolin-5(1H)-one CAS 757221-12-8

Description

2,4-Dihydro-4-pentyl-1-thioxo[1,2,4]triazolo[4,3-a]quinazolin-5(1H)-one (CAS 757221-12-8), molecular formula C14H16N4OS and molecular weight 288.37 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C14H16N4OS, 2,4-Dihydro-4-pentyl-1-thioxo[1,2,4]triazolo[4,3-a]quinazolin-5(1H)-one contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 288.37 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
