5,6,7,8-Tetrahydro-2-methyl-3-phenyl-N-(3-pyridinylmethyl)pyrazolo[5,1-b]quinazolin-9-amine CAS 896831-25-7

Description

5,6,7,8-Tetrahydro-2-methyl-3-phenyl-N-(3-pyridinylmethyl)pyrazolo[5,1-b]quinazolin-9-amine (CAS 896831-25-7) is a high-purity analytical reference standard with the molecular formula C23H23N5 and a molecular weight of 369.46 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 5,6,7,8-Tetrahydro-2-methyl-3-phenyl-N-(3-pyridinylmethyl)pyrazolo[5,1-b]quinazolin-9-amine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 369.46 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), 5,6,7,8-Tetrahydro-2-methyl-3-phenyl-N-(3-pyridinylmethyl)pyrazolo[5,1-b]quinazolin-9-amine 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.
