Chemical Structure

7-Mercapto-2-phenyl-5H-pyrazolo[1,5-d][1,2,4]-triazin-4-one CAS 842971-47-5 chemical structure

Description

As a certified reference material (CRM), 7-Mercapto-2-phenyl-5H-pyrazolo[1,5-d][1,2,4]-triazin-4-one 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.

CATO supplies 7-Mercapto-2-phenyl-5H-pyrazolo[1,5-d][1,2,4]-triazin-4-one (CAS 842971-47-5), a certified reference material (molecular formula C11H8N4OS, MW 244.27 g/mol) for analytical method development and quality control.

The molecular framework of 7-Mercapto-2-phenyl-5H-pyrazolo[1,5-d][1,2,4]-triazin-4-one (C11H8N4OS) 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.
