Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2-(Diethylamino)-N'-(diphenylmethylene)acetohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 309.41 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).
2-(Diethylamino)-N'-(diphenylmethylene)acetohydrazide (CAS 478247-23-3) is a high-purity analytical reference standard with the molecular formula C19H23N3O and a molecular weight of 309.41 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
