Chemical Structure

N-((1,3-Dimethyl-1H-pyrazol-4-yl)methyl)-1-ethyl-1H-pyrazol-4-amine hydrochloride CAS 1855951-35-7 chemical structure

Description

The occurrence of N-((1,3-Dimethyl-1H-pyrazol-4-yl)methyl)-1-ethyl-1H-pyrazol-4-amine hydrochloride is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-((1,3-Dimethyl-1H-pyrazol-4-yl)methyl)-1-ethyl-1H-pyrazol-4-amine hydrochloride (CAS 1855951-35-7) is a high-purity analytical reference standard with the molecular formula C11H17N5HCl and a molecular weight of 255.75 g/mol.

The molecular framework of N-((1,3-Dimethyl-1H-pyrazol-4-yl)methyl)-1-ethyl-1H-pyrazol-4-amine hydrochloride (C11H17N5HCl) is characterized by a nitrogen-containing heterocyclic scaffold, 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures N-((1,3-Dimethyl-1H-pyrazol-4-yl)methyl)-1-ethyl-1H-pyrazol-4-amine hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
