Chemical Structure
Description
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.
CATO supplies 3-(4-(Isopentyloxy)-3-methylphenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde (CAS 956200-16-1), a certified reference material (molecular formula C22H24N2O2, MW 348.44 g/mol) for analytical method development and quality control.
3-(4-(Isopentyloxy)-3-methylphenyl)-1-phenyl-1H-pyrazole-4-carbaldehyde (C22H24N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
