Chemical Structure
Description
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.
1-(2-(4-Bromo-2-fluorophenoxy)ethyl)-4-(2-((tert-butyldiphenylsilyl)oxy)ethyl)piperazine (CAS 1704081-76-4) is a high-purity analytical reference standard with the molecular formula C30H38BrFN2O2Si and a molecular weight of 585.62 g/mol.
Structurally, 1-(2-(4-Bromo-2-fluorophenoxy)ethyl)-4-(2-((tert-butyldiphenylsilyl)oxy)ethyl)piperazine (C30H38BrFN2O2Si) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 585.62 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
