Chemical Structure

N3,N3-Dimethyl-1H-pyrazole-3,5-diamine CAS 732981-76-9 chemical structure

Description

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

CATO supplies N3,N3-Dimethyl-1H-pyrazole-3,5-diamine (CAS 732981-76-9), a certified reference material (molecular formula C5H10N4, MW 126.16 g/mol) for analytical method development and quality control.

Owing to a nitrile group, N3,N3-Dimethyl-1H-pyrazole-3,5-diamine is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 126.16 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).

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.
