(R)-1,1-Bis(3,5-bis(trifluoromethyl)phenyl)tetrahydro-1H,3H-pyrrolo[1,2-c]oxazol-3-one CAS 1146629-85-7 chemical structure

Description

The occurrence of (R)-1,1-Bis(3,5-bis(trifluoromethyl)phenyl)tetrahydro-1H,3H-pyrrolo[1,2-c]oxazol-3-one is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (R)-1,1-Bis(3,5-bis(trifluoromethyl)phenyl)tetrahydro-1H,3H-pyrrolo[1,2-c]oxazol-3-one (CAS 1146629-85-7), a certified reference material (molecular formula C22H13F12NO2, MW 551.32 g/mol) for analytical method development and quality control.

(R)-1,1-Bis(3,5-bis(trifluoromethyl)phenyl)tetrahydro-1H,3H-pyrrolo[1,2-c]oxazol-3-one (C22H13F12NO2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), (R)-1,1-Bis(3,5-bis(trifluoromethyl)phenyl)tetrahydro-1H,3H-pyrrolo[1,2-c]oxazol-3-one 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.
