2,3-Dihydro-2-thioxo-3-(1H-1,2,4-triazol-5-yl)-4(1H)-quinazolinone CAS 131842-34-7

Description

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

2,3-Dihydro-2-thioxo-3-(1H-1,2,4-triazol-5-yl)-4(1H)-quinazolinone (CAS 131842-34-7) is a high-purity analytical reference standard with the molecular formula C10H7N5OS and a molecular weight of 245.26 g/mol.

The molecular framework of 2,3-Dihydro-2-thioxo-3-(1H-1,2,4-triazol-5-yl)-4(1H)-quinazolinone (C10H7N5OS) 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).

As a certified reference material (CRM), 2,3-Dihydro-2-thioxo-3-(1H-1,2,4-triazol-5-yl)-4(1H)-quinazolinone 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.
