3-[1-(3-Fluoro-4-methoxybenzoyl)piperidin-4-yl]-4-[(4-methoxyphenyl)methyl]-4,5-dihydro-1H-1,2,4-triazol-5-one CAS 1775559-75-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 440.47 g/mol gives 3-[1-(3-Fluoro-4-methoxybenzoyl)piperidin-4-yl]-4-[(4-methoxyphenyl)methyl]-4,5-dihydro-1H-1,2,4-triazol-5-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-[1-(3-Fluoro-4-methoxybenzoyl)piperidin-4-yl]-4-[(4-methoxyphenyl)methyl]-4,5-dihydro-1H-1,2,4-triazol-5-one (CAS 1775559-75-5), a certified reference material (molecular formula C23H25FN4O4, MW 440.47 g/mol) for analytical method development and quality control.

The molecular framework of 3-[1-(3-Fluoro-4-methoxybenzoyl)piperidin-4-yl]-4-[(4-methoxyphenyl)methyl]-4,5-dihydro-1H-1,2,4-triazol-5-one (C23H25FN4O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
