Chemical Structure
Description
CATO supplies 4-Bromo-5-(isopropoxymethyl)-1-isopropyl-1H-pyrazole (CAS 1856089-09-2), a certified reference material (molecular formula C10H17BrN2O, MW 261.16 g/mol) for analytical method development and quality control.
4-Bromo-5-(isopropoxymethyl)-1-isopropyl-1H-pyrazole (C10H17BrN2O) contains an amide group, a hydroxyl group, an ether linkage, bromine 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. 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.
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.
