Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6H,7H,8H,9H-[1,2,4]Triazolo[1,5-a]quinazolin-6-one.
CATO supplies 6H,7H,8H,9H-[1,2,4]Triazolo[1,5-a]quinazolin-6-one (CAS 29940-50-9), a certified reference material (molecular formula C9H8N4O, MW 188.19 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 6H,7H,8H,9H-[1,2,4]Triazolo[1,5-a]quinazolin-6-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 188.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), 6H,7H,8H,9H-[1,2,4]Triazolo[1,5-a]quinazolin-6-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.
