Chemical Structure

1-(Cyclopropylmethyl)-4-methyl-1h-pyrazol-5-amine hydrochloride CAS 1221723-28-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 187.67 g/mol gives 1-(Cyclopropylmethyl)-4-methyl-1h-pyrazol-5-amine hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

1-(Cyclopropylmethyl)-4-methyl-1h-pyrazol-5-amine hydrochloride (CAS 1221723-28-9) is a high-purity analytical reference standard with the molecular formula C8H13N3HCl and a molecular weight of 187.67 g/mol.

The molecular framework of 1-(Cyclopropylmethyl)-4-methyl-1h-pyrazol-5-amine hydrochloride (C8H13N3HCl) is characterized by a nitrile group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
