4-Phenyl-4,5-dihydro-1H-chromeno[4,3-d]pyrimidin-2-amine CAS 646063-20-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-Phenyl-4,5-dihydro-1H-chromeno[4,3-d]pyrimidin-2-amine.

4-Phenyl-4,5-dihydro-1H-chromeno[4,3-d]pyrimidin-2-amine (CAS 646063-20-9), molecular formula C17H15N3O and molecular weight 277.32 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4-Phenyl-4,5-dihydro-1H-chromeno[4,3-d]pyrimidin-2-amine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 277.32 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).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
