1-(3-Cyclohexyl-1-methyl-5-vinyl-1H-pyrazol-4-yl)-2-methylpropan-1-one CAS 1956381-68-2

Description

Compared with other compounds in its class, the molecular weight of 260.37 g/mol gives 1-(3-Cyclohexyl-1-methyl-5-vinyl-1H-pyrazol-4-yl)-2-methylpropan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(3-Cyclohexyl-1-methyl-5-vinyl-1H-pyrazol-4-yl)-2-methylpropan-1-one (CAS 1956381-68-2), molecular formula C16H24N2O and molecular weight 260.37 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 1-(3-Cyclohexyl-1-methyl-5-vinyl-1H-pyrazol-4-yl)-2-methylpropan-1-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 260.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
