Chemical Structure
Description
344934-45-8 KS-00001ZP7 N'-[(Z)-(2-chlorophenyl)methylidene]-2-(1H-pyrrol-1-yl)benzenecarbohydrazide (CAS 344934-45-8) is a high-purity analytical reference standard with the molecular formula C18H14ClN3O and a molecular weight of 323.78 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 344934-45-8 KS-00001ZP7 N'-[(Z)-(2-chlorophenyl)methylidene]-2-(1H-pyrrol-1-yl)benzenecarbohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 323.78 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.
