4-((5-Methylpyrazin-2-yl)amino)quinazolin-6-ol CAS 865664-02-4

Description

The occurrence of 4-((5-Methylpyrazin-2-yl)amino)quinazolin-6-ol 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.

4-((5-Methylpyrazin-2-yl)amino)quinazolin-6-ol (CAS 865664-02-4) is a high-purity analytical reference standard with the molecular formula C13H11N5O and a molecular weight of 253.26 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 4-((5-Methylpyrazin-2-yl)amino)quinazolin-6-ol is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 253.26 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).
