3,5-Dimethyl-1-(pyridin-2-yl)-1H-pyrazole CAS 21018-71-3

Description

Compared with other compounds in its class, the molecular weight of 173.21 g/mol gives 3,5-Dimethyl-1-(pyridin-2-yl)-1H-pyrazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3,5-Dimethyl-1-(pyridin-2-yl)-1H-pyrazole (CAS 21018-71-3), a certified reference material (molecular formula C10H11N3, MW 173.21 g/mol) for analytical method development and quality control.

3,5-Dimethyl-1-(pyridin-2-yl)-1H-pyrazole (C10H11N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
