Compared with other compounds in its class, the molecular weight of 232.26 g/mol gives 1-mercapto-4-methyl[1,2,4]triazolo[4,3-a]quinazolin-5(4H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-mercapto-4-methyl[1,2,4]triazolo[4,3-a]quinazolin-5(4H)-one (CAS 127570-96-1) is a high-purity analytical reference standard with the molecular formula C10H8N4OS and a molecular weight of 232.26 g/mol.
The molecular framework of 1-mercapto-4-methyl[1,2,4]triazolo[4,3-a]quinazolin-5(4H)-one (C10H8N4OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
