Chemical Structure

5-Propylpyrazole-3-carboxamide CAS 957129-48-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 153.18 g/mol gives 5-Propylpyrazole-3-carboxamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Propylpyrazole-3-carboxamide (CAS 957129-48-5), molecular formula C7H11N3O and molecular weight 153.18 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C7H11N3O, 5-Propylpyrazole-3-carboxamide contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 153.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
