2-Mercapto-4(3<I>H</I>)-quinazolone CAS 13906-09-7

Description

Compared with other compounds in its class, the molecular weight of 184.26 g/mol gives 2-Mercapto-4(3<I>H</I>)-quinazolone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Mercapto-4(3<I>H</I>)-quinazolone (CAS 13906-09-7), molecular formula C8H12N2OS and molecular weight 184.26 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Mercapto-4(3<I>H</I>)-quinazolone (C8H12N2OS) 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 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 2-Mercapto-4(3<I>H</I>)-quinazolone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
