3-(tert-Butyl)-5-isopropyl-1H-pyrazole CAS 194366-44-4

Description

Compared with other compounds in its class, the molecular weight of 166.26 g/mol gives 3-(tert-Butyl)-5-isopropyl-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-(tert-Butyl)-5-isopropyl-1H-pyrazole (CAS 194366-44-4) is a high-purity analytical reference standard with the molecular formula C10H18N2 and a molecular weight of 166.26 g/mol.

Owing to a nitrile group, 3-(tert-Butyl)-5-isopropyl-1H-pyrazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 166.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
