1-Mercapto-4-p-tolyl-4H-[1,2,4]triazolo[4,3-a]quinazolin-5-one CAS 67442-92-6

Description

As a certified reference material (CRM), 1-Mercapto-4-p-tolyl-4H-[1,2,4]triazolo[4,3-a]quinazolin-5-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 1-Mercapto-4-p-tolyl-4H-[1,2,4]triazolo[4,3-a]quinazolin-5-one (CAS 67442-92-6), a certified reference material (molecular formula C16H12N4OS, MW 308.36 g/mol) for analytical method development and quality control.

The molecular framework of 1-Mercapto-4-p-tolyl-4H-[1,2,4]triazolo[4,3-a]quinazolin-5-one (C16H12N4OS) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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