Chemical Structure

3-Nonyl-4-octyl-1H-pyrazol-5(4H)-one CAS 91990-64-6 chemical structure

Description

Owing to an amide group, a hydroxyl group, an ether linkage, 3-Nonyl-4-octyl-1H-pyrazol-5(4H)-one is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 322.53 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

3-Nonyl-4-octyl-1H-pyrazol-5(4H)-one (CAS 91990-64-6) is a high-purity analytical reference standard with the molecular formula C20H38N2O and a molecular weight of 322.53 g/mol.

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.
