1-(2-Fluorophenyl)-3-hydroxy-3-methylurea CAS 56935-02-5

Description

1-(2-Fluorophenyl)-3-hydroxy-3-methylurea (C8H9FN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

1-(2-Fluorophenyl)-3-hydroxy-3-methylurea (CAS 56935-02-5) is a high-purity analytical reference standard with the molecular formula C8H9FN2O2 and a molecular weight of 184.17 g/mol.

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), 1-(2-Fluorophenyl)-3-hydroxy-3-methylurea 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.
