Chemical Structure
Description
Structurally, tert-Butyl (2-(4-bromo-2-fluorophenoxy)ethyl)(cyclopentyl)carbamate (C18H25BrFNO3) 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 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 402.30 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies tert-Butyl (2-(4-bromo-2-fluorophenoxy)ethyl)(cyclopentyl)carbamate (CAS 1704095-94-2), a certified reference material (molecular formula C18H25BrFNO3, MW 402.30 g/mol) for analytical method development and quality control.
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.
