3-Amino-2-(methylthio)quinazolin-4(3H)-one CAS 261509-54-0

Description

Compared with other compounds in its class, the molecular weight of 207.25 g/mol gives 3-Amino-2-(methylthio)quinazolin-4(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Amino-2-(methylthio)quinazolin-4(3H)-one (CAS 261509-54-0), molecular formula C9H9N3OS and molecular weight 207.25 g/mol, is a CATO reference standard with documented purity and traceability.

3-Amino-2-(methylthio)quinazolin-4(3H)-one (C9H9N3OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
