Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 125.13 g/mol gives 1-(1-Methyl-1H-1,2,4-triazol-3-yl)ethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(1-Methyl-1H-1,2,4-triazol-3-yl)ethan-1-one (CAS 153334-38-4) is a high-purity analytical reference standard with the molecular formula C5H7N3O and a molecular weight of 125.13 g/mol.
The molecular framework of 1-(1-Methyl-1H-1,2,4-triazol-3-yl)ethan-1-one (C5H7N3O) is characterized by 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
