Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 170.17 g/mol gives Ethyl 2-(3-oxo-2,3-dihydro-1h-pyrazol-4-yl)acetate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 2-(3-oxo-2,3-dihydro-1h-pyrazol-4-yl)acetate (CAS 890095-13-3), molecular formula C7H10N2O3 and molecular weight 170.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 2-(3-oxo-2,3-dihydro-1h-pyrazol-4-yl)acetate (C7H10N2O3) is characterized by an amino-acid-derived structure, 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.
