Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 137.18 g/mol gives 1-Cyclopropyl-5-methyl-1H-pyrazol-3-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-Cyclopropyl-5-methyl-1H-pyrazol-3-amine (CAS 1240570-44-8), a certified reference material (molecular formula C7H11N3, MW 137.18 g/mol) for analytical method development and quality control.
Owing to a nitrile group, an aromatic ring system, 1-Cyclopropyl-5-methyl-1H-pyrazol-3-amine is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 137.18 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.
