Chemical Structure
Description
The occurrence of (E)-4-((morpholinoimino)methyl)-5-(trifluoromethyl)-1,2-dihydro-3H-pyrazol-3-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(E)-4-((morpholinoimino)methyl)-5-(trifluoromethyl)-1,2-dihydro-3H-pyrazol-3-one (CAS 240115-95-1) is a high-purity analytical reference standard with the molecular formula C9H11F3N4O2 and a molecular weight of 264.20 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, (E)-4-((morpholinoimino)methyl)-5-(trifluoromethyl)-1,2-dihydro-3H-pyrazol-3-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 264.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
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.
