Chemical Structure

3-phenyl-4-(trifluoromethyl)isoxaZolo[5,4-b]pyridin-6(7h)-one CAS 1018047-90-9 chemical structure

Description

The occurrence of 3-phenyl-4-(trifluoromethyl)isoxaZolo[5,4-b]pyridin-6(7h)-one is closely related to a nitrogen-containing heterocyclic scaffold, 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 3-phenyl-4-(trifluoromethyl)isoxaZolo[5,4-b]pyridin-6(7h)-one (CAS 1018047-90-9), a certified reference material (molecular formula C13H7F3N2O2, MW 280.20 g/mol) for analytical method development and quality control.

Structurally, 3-phenyl-4-(trifluoromethyl)isoxaZolo[5,4-b]pyridin-6(7h)-one (C13H7F3N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 280.20 g/mol, it falls into the medium-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.

CATO manufactures 3-phenyl-4-(trifluoromethyl)isoxaZolo[5,4-b]pyridin-6(7h)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
