6-Benzyl-2-phenyl-5,6,7,8-tetrahydro-3H-pyrido[4,3-d]pyrimidin-4-one CAS 1047-48-9

Description

The occurrence of 6-Benzyl-2-phenyl-5,6,7,8-tetrahydro-3H-pyrido[4,3-d]pyrimidin-4-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-Benzyl-2-phenyl-5,6,7,8-tetrahydro-3H-pyrido[4,3-d]pyrimidin-4-one (CAS 1047-48-9) is a high-purity analytical reference standard with the molecular formula C20H19N3O and a molecular weight of 317.38 g/mol.

Structurally, 6-Benzyl-2-phenyl-5,6,7,8-tetrahydro-3H-pyrido[4,3-d]pyrimidin-4-one (C20H19N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 317.38 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
