1-(3,5-Dimethyl-1H-pyrazol-1-yl)-2-(5-(thiophen-2-yl)-1,3,4-oxadiazol-2-yl)ethan-1-one CAS 1707392-23-1

Description

The occurrence of 1-(3,5-Dimethyl-1H-pyrazol-1-yl)-2-(5-(thiophen-2-yl)-1,3,4-oxadiazol-2-yl)ethan-1-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(3,5-Dimethyl-1H-pyrazol-1-yl)-2-(5-(thiophen-2-yl)-1,3,4-oxadiazol-2-yl)ethan-1-one (CAS 1707392-23-1), molecular formula C13H12N4O2S and molecular weight 288.32 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-(3,5-Dimethyl-1H-pyrazol-1-yl)-2-(5-(thiophen-2-yl)-1,3,4-oxadiazol-2-yl)ethan-1-one (C13H12N4O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), 1-(3,5-Dimethyl-1H-pyrazol-1-yl)-2-(5-(thiophen-2-yl)-1,3,4-oxadiazol-2-yl)ethan-1-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
