Chemical Structure
Description
The occurrence of (1Z)-5-(2,6-Dichlorophenyl)-1-(dimethylamino)-4-[(2E)-3-(dimethylamino)prop-2-enoyl]pent-1-en-3-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(1Z)-5-(2,6-Dichlorophenyl)-1-(dimethylamino)-4-[(2E)-3-(dimethylamino)prop-2-enoyl]pent-1-en-3-one (CAS 672951-53-0), molecular formula C18H22Cl2N2O2 and molecular weight 369.29 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (1Z)-5-(2,6-Dichlorophenyl)-1-(dimethylamino)-4-[(2E)-3-(dimethylamino)prop-2-enoyl]pent-1-en-3-one (C18H22Cl2N2O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 369.29 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).
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.
