Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-(((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)amino)methyl)-4,5-dihydroisoxazole-3-carbohydrazide (CAS 251310-32-4) is a high-purity analytical reference standard with the molecular formula C11H11ClF3N5O2 and a molecular weight of 337.69 g/mol.
Based on its molecular formula C11H11ClF3N5O2, 5-(((3-Chloro-5-(trifluoromethyl)pyridin-2-yl)amino)methyl)-4,5-dihydroisoxazole-3-carbohydrazide contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 337.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
