Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5,6-Dihydrobenzo[h]quinazolin-2-ol.
CATO supplies 5,6-Dihydrobenzo[h]quinazolin-2-ol (CAS 4786-77-0), a certified reference material (molecular formula C12H10N2O, MW 198.22 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, 5,6-Dihydrobenzo[h]quinazolin-2-ol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 198.22 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), 5,6-Dihydrobenzo[h]quinazolin-2-ol 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.
