Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(3,4-Dichlorophenyl)-2-(2,3-dihydro-1h-inden-5-yloxy)ethan-1-one.
1-(3,4-Dichlorophenyl)-2-(2,3-dihydro-1h-inden-5-yloxy)ethan-1-one (CAS 1154284-20-4) is a high-purity analytical reference standard with the molecular formula C17H14Cl2O2 and a molecular weight of 321.20 g/mol.
Structurally, 1-(3,4-Dichlorophenyl)-2-(2,3-dihydro-1h-inden-5-yloxy)ethan-1-one (C17H14Cl2O2) contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 321.20 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
