Chemical Structure
Description
Structurally, (E)-3-Chloro-N'-hydroxy-N-[(pyridin-3-yl)methyl]-5-(trifluoromethyl)pyridine-2-carboximidamide (C13H10ClF3N4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 330.69 g/mol, it falls into the moderately-high-molecular-weight range. 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).
(E)-3-Chloro-N'-hydroxy-N-[(pyridin-3-yl)methyl]-5-(trifluoromethyl)pyridine-2-carboximidamide (CAS 320420-32-4), molecular formula C13H10ClF3N4O and molecular weight 330.69 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
