Chemical Structure
Description
tert-butyl 3-(4-fluorophenyl)morpholine-4-carboxylate (CAS 1909337-32-1), molecular formula C15H20FNO3 and molecular weight 281.32 g/mol, is a CATO reference standard with documented purity and traceability.
tert-butyl 3-(4-fluorophenyl)morpholine-4-carboxylate (C15H20FNO3) contains a nitrogen-containing heterocyclic scaffold, 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.
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), tert-butyl 3-(4-fluorophenyl)morpholine-4-carboxylate 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.
