N-(tert-butyl)-1-methyl-1H-pyrazole-4-carboxamide CAS 1197530-35-0

Description

Compared with other compounds in its class, the molecular weight of 181.23 g/mol gives N-(tert-butyl)-1-methyl-1H-pyrazole-4-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N-(tert-butyl)-1-methyl-1H-pyrazole-4-carboxamide (CAS 1197530-35-0) is a high-purity analytical reference standard with the molecular formula C9H15N3O and a molecular weight of 181.23 g/mol.

The molecular framework of N-(tert-butyl)-1-methyl-1H-pyrazole-4-carboxamide (C9H15N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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.
