Chemical Structure
Description
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 supplies 1-(4-Fluoro-phenyl)-3,5-dimethyl-1H-pyrazole-4-carbaldehyde 2217AF 890626-54-7 C12H11FN2O (CAS 890626-54-7), a certified reference material (molecular formula C12H21FN2O, MW 228.31 g/mol) for analytical method development and quality control.
The molecular framework of 1-(4-Fluoro-phenyl)-3,5-dimethyl-1H-pyrazole-4-carbaldehyde 2217AF 890626-54-7 C12H11FN2O (C12H21FN2O) is characterized by an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
