1-Ethyl-3-methyl-N-(5-(phenoxymethyl)-1,3,4-oxadiazol-2-yl)-1H-pyrazole-5-carboxamide CAS 1286696-41-0 chemical structure

Description

The occurrence of 1-Ethyl-3-methyl-N-(5-(phenoxymethyl)-1,3,4-oxadiazol-2-yl)-1H-pyrazole-5-carboxamide is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-Ethyl-3-methyl-N-(5-(phenoxymethyl)-1,3,4-oxadiazol-2-yl)-1H-pyrazole-5-carboxamide (CAS 1286696-41-0) is a high-purity analytical reference standard with the molecular formula C16H17N5O3 and a molecular weight of 327.34 g/mol.

The molecular framework of 1-Ethyl-3-methyl-N-(5-(phenoxymethyl)-1,3,4-oxadiazol-2-yl)-1H-pyrazole-5-carboxamide (C16H17N5O3) 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.
