1-(3-Iodo-1-isopropyl-1H-pyrazol-4-yl)ethan-1-one CAS 1269440-49-4

Description

Compared with other compounds in its class, the molecular weight of 278.09 g/mol gives 1-(3-Iodo-1-isopropyl-1H-pyrazol-4-yl)ethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-(3-Iodo-1-isopropyl-1H-pyrazol-4-yl)ethan-1-one (CAS 1269440-49-4), a certified reference material (molecular formula C8H11IN2O, MW 278.09 g/mol) for analytical method development and quality control.

1-(3-Iodo-1-isopropyl-1H-pyrazol-4-yl)ethan-1-one (C8H11IN2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, iodine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
