(E)-N-{5H-chromeno[4,3-d]pyrimidin-2-yl}-N'-[(4-fluorophenyl)methoxy]methanimidamide CAS 866142-93-0 chemical structure

Description

The occurrence of (E)-N-{5H-chromeno[4,3-d]pyrimidin-2-yl}-N'-[(4-fluorophenyl)methoxy]methanimidamide is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (E)-N-{5H-chromeno[4,3-d]pyrimidin-2-yl}-N'-[(4-fluorophenyl)methoxy]methanimidamide (CAS 866142-93-0), a certified reference material (molecular formula C19H15FN4O2, MW 350.35 g/mol) for analytical method development and quality control.

Structurally, (E)-N-{5H-chromeno[4,3-d]pyrimidin-2-yl}-N'-[(4-fluorophenyl)methoxy]methanimidamide (C19H15FN4O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 350.35 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
