Chemical Structure
Description
The occurrence of (4S)-2-[2-[Bis[3,5-bis(trifluoromethyl)phenyl]phosphino]phenyl]-4,5-dihydro-4-(1-methylethyl)oxazole is closely related to a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(4S)-2-[2-[Bis[3,5-bis(trifluoromethyl)phenyl]phosphino]phenyl]-4,5-dihydro-4-(1-methylethyl)oxazole (CAS 180260-73-5), molecular formula C28H20F12NOP and molecular weight 645.42 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine substitution, (4S)-2-[2-[Bis[3,5-bis(trifluoromethyl)phenyl]phosphino]phenyl]-4,5-dihydro-4-(1-methylethyl)oxazole is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 645.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures (4S)-2-[2-[Bis[3,5-bis(trifluoromethyl)phenyl]phosphino]phenyl]-4,5-dihydro-4-(1-methylethyl)oxazole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
