Chemical Structure
Description
2-(diphenylacetyl)-3-hydrazino-1H-Inden-1-one (CAS 138039-82-4) is a high-purity analytical reference standard with the molecular formula C23H18N2O2 and a molecular weight of 354.40 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2-(diphenylacetyl)-3-hydrazino-1H-Inden-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 354.40 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.
