4-((4-Methoxyphenyl)amino)-2,6-diphenylpyrimidine-5-carbonitrile CAS 64499-36-1 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-((4-Methoxyphenyl)amino)-2,6-diphenylpyrimidine-5-carbonitrile.

4-((4-Methoxyphenyl)amino)-2,6-diphenylpyrimidine-5-carbonitrile (CAS 64499-36-1), molecular formula C24H18N4O and molecular weight 378.43 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 4-((4-Methoxyphenyl)amino)-2,6-diphenylpyrimidine-5-carbonitrile (C24H18N4O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 18.0, corresponding to approximately 18 ring(s) or double-bond equivalent(s). With a molecular weight of 378.43 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
