Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(3E)-3-{[(2,4-dichlorophenyl)methoxy]imino}-1-{4-[(2,4-dichlorophenyl)methoxy]phenyl}propan-1-one (CAS 478033-84-0) is a high-purity analytical reference standard with the molecular formula C23H17Cl4NO3 and a molecular weight of 497.20 g/mol.
Structurally, (3E)-3-{[(2,4-dichlorophenyl)methoxy]imino}-1-{4-[(2,4-dichlorophenyl)methoxy]phenyl}propan-1-one (C23H17Cl4NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 497.20 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).
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.
