Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 2-(8-bromo-1,3-difluorophenanthren-2-yl)-2,3,3,3-tetrafluoropropanoate.
CATO supplies Ethyl 2-(8-bromo-1,3-difluorophenanthren-2-yl)-2,3,3,3-tetrafluoropropanoate (CAS 843614-94-8), a certified reference material (molecular formula C19H11BrF6O2, MW 465.18 g/mol) for analytical method development and quality control.
Ethyl 2-(8-bromo-1,3-difluorophenanthren-2-yl)-2,3,3,3-tetrafluoropropanoate (C19H11BrF6O2) contains a steroid core, a hydroxyl group, an ether linkage, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), Ethyl 2-(8-bromo-1,3-difluorophenanthren-2-yl)-2,3,3,3-tetrafluoropropanoate 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.
