Chemical Structure
Description
4-(5-Bromo-2,3-difluorophenyl)morpholine (CAS 1129540-95-9), molecular formula C10H10BrF2NO and molecular weight 278.09 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, 4-(5-Bromo-2,3-difluorophenyl)morpholine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 278.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), 4-(5-Bromo-2,3-difluorophenyl)morpholine 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.
