N-Cyclopropyl-3-fluoro-5-(1H-indazol-5-yl)-4-methylbenzamide CAS 651780-48-2

Description

CATO supplies N-Cyclopropyl-3-fluoro-5-(1H-indazol-5-yl)-4-methylbenzamide (CAS 651780-48-2), a certified reference material (molecular formula C18H16FN3O, MW 309.34 g/mol) for analytical method development and quality control.

N-Cyclopropyl-3-fluoro-5-(1H-indazol-5-yl)-4-methylbenzamide (C18H16FN3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
