Chemical Structure
Description
CATO supplies tert-Butyl (3-phenyl-3-(4-(trifluoromethyl)phenoxy)propyl)carbamate (CAS 257892-44-7), a certified reference material (molecular formula C21H24F3NO3, MW 395.42 g/mol) for analytical method development and quality control.
tert-Butyl (3-phenyl-3-(4-(trifluoromethyl)phenoxy)propyl)carbamate (C21H24F3NO3) 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. 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.
As a certified reference material (CRM), tert-Butyl (3-phenyl-3-(4-(trifluoromethyl)phenoxy)propyl)carbamate 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.
