8-Methyl-1,11-dihydro-2H-pyrimido[4,5-a]carbazol-2-one CAS 248246-44-8

Description

The occurrence of 8-Methyl-1,11-dihydro-2H-pyrimido[4,5-a]carbazol-2-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 8-Methyl-1,11-dihydro-2H-pyrimido[4,5-a]carbazol-2-one (CAS 248246-44-8), a certified reference material (molecular formula C15H11N3O, MW 249.27 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, 8-Methyl-1,11-dihydro-2H-pyrimido[4,5-a]carbazol-2-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 249.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), 8-Methyl-1,11-dihydro-2H-pyrimido[4,5-a]carbazol-2-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.
