Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (5-Fluoro-2-hydroxyphenyl)diphenylphosphineoxide (CAS 1592980-04-5), a certified reference material (molecular formula C18H14FO2P, MW 312.27 g/mol) for analytical method development and quality control.
Owing to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution, (5-Fluoro-2-hydroxyphenyl)diphenylphosphineoxide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 312.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), (5-Fluoro-2-hydroxyphenyl)diphenylphosphineoxide 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.
