Chemical Structure
Description
The occurrence of Fulvestrant Impurity 47 is closely related to a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Fulvestrant Impurity 47 (CAS 96044-45-0), a certified reference material (molecular formula C16H35BrOSi, MW 351.44 g/mol) for analytical method development and quality control.
Structurally, Fulvestrant Impurity 47 (C16H35BrOSi) contains a hydroxyl group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 351.44 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.
As a certified reference material (CRM), Fulvestrant Impurity 47 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
