Chemical Structure

5-Methyl-1-(propan-2-yl)-1h-pyrazole CAS 160729-59-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Methyl-1-(propan-2-yl)-1h-pyrazole.

5-Methyl-1-(propan-2-yl)-1h-pyrazole (CAS 160729-59-9) is a high-purity analytical reference standard with the molecular formula C7H12N2 and a molecular weight of 124.18 g/mol.

Owing to a nitrile group, 5-Methyl-1-(propan-2-yl)-1h-pyrazole is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 124.18 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).

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.
